NEWSFLASH! Most Brits don’t know how to make tea!


Cor, I’m gobsmacked! The world’s gone barmy! The Telegraph, that bastion of Britishness, has declared in no uncertain terms that 80% of Britons don’t know how to make tea! Not only that, it’s scientists that say so. Scientists! Why, just look at the headline:

Telegraph Article

Okay, let’s all just keep calm and carry on here. I have certainly addressed the subject of making the perfect cup of tea before. And scientists have weighed in, too. Why, there’s a British standards document from the Royal Society of Chemistry that explains it step by step. Even George Orwell defined the ideal cup (although I disagree with him).

Keep Calm and Make Tea (properly)

So how do we deal with this gormless assertion from The Telegraph? We shall take it one item at a time, beginning with the definition of knowing how to make a cup of tea.

You see, the world is filled with tea Nazis: people who aren’t happy with figuring out how to make their tea; they have the cheek to tell you how to make your tea. I am a much more mellow fellow myself. I believe that if you make a cup of tea and you enjoy it, you’re doing it right. You may not be doing it my way, or the Royal Society of Chemistry’s way, or George Orwell’s way, but you’re doing it in a way that makes you happy. It doesn’t get much more “right” than that.

But let’s set my sappy altruism aside for a moment and examine what The Telegraph and the scientists at University College London have to say. They do, as it turns out, have some quite valid assertions — although their science reporter may have been a bit hasty in his conclusions.

“Despite drinking 165 million cups of tea each day, scientists believe that most Brits do not allow the leaves to infuse long enough for the complex flavours to emerge. Researchers at University College London and the British Science Association claim tea must be allowed to steep for up to five minutes, far longer than the toe-tapping two minutes allowed by most drinkers.”

I’m going to start out by making an assumption here, and that is that we’re specifically talking about black tea. I make my assumption based on the fact that their entire article assumes you’re adding milk to your tea (I have never met anyone who added milk to white or green tea, although I did meet one sad little man who put milk in his oolong), and that you’re using boiling water, which is perfect for black tea or pu-erh but ruins white or green tea.

One of the characteristics prized by British tea aficionados is astringency (which Lipton’s calls “briskness”). Your average breakfast tea in the U.K. is steeped until it is quite “brisk” (which I call undrinkably bitter). The astringency is then cut with milk, and possibly sugar as well. Generally speaking, when I want milk I drink a glass of milk. When I want tea, I want it to taste like tea. I take mine black, which means I use shorter steep times to control the astringency.

“And they advise using a pot rather than a tea-bag in a mug to allow convection currents to swirl tea leaves fully through the water.”

Okay, I have to agree with them there. Teabags are evil, and here’s why:

no teabags

Dried tea leaves swell as you steep them. To extract the maximum flavor (and caffeine, and antioxidants…) from the leaves, they need water flow around them. Teabags were introduced for convenience, and they are, indeed, convenient. On the downside, though, they don’t give the leaves room to swell, and they severely limit the flow of water around the leaves. To address this problem, tea makers generally don’t put high-quality whole-leaf tea in the bags. Instead, they use finely crushed leaves, known as “fannings” or “dust.” This increases the surface area exposed to water, allows them to make the bags smaller, and (here’s the evil part) use the lowest-quality tea that was passed over by all of the tea makers that buy whole leaf — what I refer to as “floor sweepings.”

The article goes on to quote Mark Miodownik, Professor of Materials and Society at University College London:

“It’s obviously subjective but I feel people are missing out on a drink which could be so much more sophisticated because they don’t wait for the tea to brew long enough. Tea is made of 30,000 different chemicals, it’s a very complex thing and those molecules take time to emerge and influence each other.”

He could well have stopped after the first three words. It is obviously subjective, indeed. Perhaps the first 10,000 chemicals that emerge are the ones you find tastiest, and the last 10,000 are the ones that I prefer. Should we both steep our tea the same? Of course not.

On an unrelated note, I sometimes feel that my formal training in electrical engineering and computer science does not really qualify me to speak as an expert on tea. Seeing The Telegraph quote a professor of “materials and society” as a tea expert makes me feel better.

Back to the point at hand, Mr. Miodownik goes on to say something that reinforces my point from above:

“Fair enough if you want a hot milky drink, but then why drink tea?”

The article explains that the UCL people have an answer to the question of whether the milk should be added before or after the tea is poured. They don’t, however, address the issue of whether the milk should be there in the first place. That’s because it’s subjective. Some of us prefer tea, instead of hot milky drinks!

I also particularly enjoyed their discussion of a tea study by a milk company, which quite refutes the premise of the article.

A study carried out by Cravendale milk in 2011 found that the perfect cup of tea needed eight minutes (two minutes with the tea bag or leaves, six more afterwards) before it reaches optimum flavour and temperature.

UCL tells us that tea must be steeped “far longer than the toe-tapping two minutes allowed by most drinkers,” but Cravendale says that a two minute steep is just fine as long as it can sit in milk for six minutes after it is steeped.

So who do we believe? The scientists or the milk company?

How about neither?

Make your tea the way you like to make it. Steep it until it tastes good. If you want to add milk, cream, lemon, sugar, ice cubes, honey sticks, a sprig of mint, a dash of cinnamon, or a soupçon of cayenne, then by all means do so.

As for me, I shall eschew teabags, brew my favorite black tea for 2:30 to 3:00, and sip it straight.


As I write this, I am drinking an 8-year-old aged shu (“ripe”) pu-erh tea from Vital Tea Leaf in Seattle. I started by doing a 20-second “wash,” swirling the leaves in boiling water and then pouring it off. My first infusion was 2:00, and the second was 2:30, as I wanted it a bit stronger. Proper British tea drinkers may want to stop reading now, as I steeped it neither in a mug nor a ceramic teapot, but in a brewing device made of (*gasp*) plastic. After drinking rich, earthy teas like this, it’s hard to go back to plain black tea!

Tea Lattes


The coffee industry would have you believe that the word “latte” means “espresso with steamed milk.” That basically is what “caffelatte” means, but “latte” just means “milk” in Italian. A tea latte is every bit as much a latte as a coffee latte, and the growing popularity of masala chai lattes has been bringing that point home to coffee drinkers of late. In the coffee world, a latte is typically made by preparing the espresso, mixing in the milk, and then adding foam on top. The milk is there to add flavor and to cut the espresso so it doesn’t taste as strong. In the tea world, the milk serves a somewhat different purpose. For the record here, I am not talking about Starbucks-style chai lattes, which are made with a sweet syrup. I’m talking about tea that’s fresh-brewed in milk and water.

Flavors and nutrients from tea leaves extract well in water. That’s why a straight cup of tea tastes so good. That’s why people who like milk in their tea traditionally add the milk after the tea is brewed. A lot of other things, however, don’t extract quite as well.

Many of the flavors in a masala spice blend (no, they aren’t chai spices; chai just means “tea” in Punjabi) are lipophilic. Directly translated, this means “fat-loving,” which means that they extract much better in fats (e.g., milk) than in water. That’s why it’s important to brew the masala chai in hot milk and water instead of just adding the milk later. In my tea bar, we’ve done side-by-side taste tests of tea lattes made both ways. We use a milk heater/frother instead of using the steamer that’s found on commercial espresso machines.

We tried steeping the tea in water and then adding the frothed milk vs steeping the tea in a 50/50 blend of hot water and frothed milk. In this entirely subjective set of tests using our employees and customers, the lattes brewed with milk won consistently. I realize that our production method wouldn’t work in a typical coffee shop where people are rushing in and out on their way to work. They want their drink now. They don’t want to wait four to seven minutes for a fresh-brewed cup. But in a tea bar like mine, things are different. We make a lot of lattes: close to 1/3 of all of the cups we serve. We offer a choice of milk (nonfat, 2%, whole, half-and-half, soy, almond…) and over 150 different types of tea.

Capresso frothPRO
Capresso frothPRO milk heater and frother.

The majority of our lattes are served unsweetened. For those who want it sweetened, however, we do the same thing we do when making traditional sweet tea: we add the sweetener when we’re brewing instead of at the end. Most of our customers go for either plain sugar or agave nectar, but we offer other options there, too: flavored hail sugars, honey, stevia leaf, stevia powder, and other artificial sweeteners. You can’t do something like this in a fast-moving production line environment, but you can do it at home.

A milk heater/frother is less expensive than a high-end home coffeemaker. We started out with Keurig units, but found they didn’t hold up to commercial use. There were too many fragile parts, and most of them broke in the first six months (that Keurig unit didn’t even end up on a list of the top 10 frothers this year). We switched to the Capresso frothPRO and we’ve been quite happy with them. They aren’t the fastest solution, but they’re solid, reliable, and easy-to-clean. It’s also easy to switch between heating/frothing and just heating.

If you don’t want to invest $50-$100 in a frother/heater, there’s another solution that works great at home. Just heat the milk in the microwave. Don’t let it go to a boil, but get it as hot as you can without boiling it. There are quite a few handheld battery-powered electric whisks available if you like it frothy; the list I linked in the previous paragraph includes three of them.

Battery Powered Whisk

How do you know which types of tea work best in a latte? Experiment. One of the most popular tea lattes is called a London Fog. It’s very straightforward: just Earl Grey tea and a 50/50 mix of milk and tea. We usually start the tea steeping in water and add the milk halfway through. Make sure you use the right amount of tea leaf for the total volume of milk and water; if you’re using 8 oz of milk and 8 oz of water, use enough leaf for a 16 oz mug. Many of our blends with cinnamon make good lattes, as do fruity teas. We use sweetened matcha powder for our green tea lattes. Want something different? Try making a strong shu pu-erh latte with chocolate milk. Experiment, have fun, and then teach all of your coffee-drinking friends just how many kinds of latte there are!

Making traditional masala chai at home


Before we address the topic at hand, may I take a moment to get something off of my chest?

Today we are discussing a tea called masala chai. The word “masala” refers to a yummy blend of spices, often containing cardamom, ginger, and pepper. The word “chai” means “tea” in Hindi (and Urdu, and Russian, and Bulgarian, and Aramaic, and Swahili, and a variety of other languages). Therefore, when you refer to “chai tea,” you’re talking about “tea tea.” Although most Americans call masala chai just “chai,” they really should be calling it “masala” or “masala tea” if they don’t want to say “masala chai.”

We can thank the coffee industry for confusing our terminology a couple of decades ago, as they coined the phrase “chai latte” to differentiate masala chai (traditionally made with milk) from coffee lattes. Your other word of the week is “latte,” which just means “with milk” and has nothing whatsoever to do with coffee. Tea made with heated and frothed milk is a latte, too!

Thank you. I feel better now. On to the aforementioned topic at hand:

Masala Chai Latte
You can keep your hot chocolate. I’ll take a delicious masala chai latte on a snowy day!

I would never presume to tell you the right way to make a cup of tea. As I’ve mentioned so many times before, there is no single right way to do it. In this post, however, I will talk about one of the traditional ways to make masala chai. In India, where this concoction (or decoction, if you prefer) originated, it is almost always made with milk and sugar.

In a coffee shop, masala chai (which they usually call a chai latte) is almost always made from a pre-sweetened concentrate. It’s quick and easy to make, and it tastes pretty good. But it doesn’t taste like authentic masala chai.

In a tea shop, masala chai is usually brewed fresh from a blend of black tea leaves and masala spices. If they add milk, it is usually poured in after the tea is brewed, unless the tea shop is specifically set up for lattes. You get that fresh-brewed taste, but somehow the spices don’t seem quite right to me (my tea bar does it differently, but that’s a topic for another post).

At home, you can make it the way they do in India.

The masala spices

First of all, the masala spice mix and the tea (chai) are usually purchased and stored separately. Just as many Americans have a family chili or soup or cookie recipe, many Indian families have their own masala recipe handed down through the generations. You can research and experiment to come up with your own, or go to your favorite tea shop and see if they have a blend for sale. Many tea shops (including mine) will sell you the masala spice mix they use in-house without the tea.

If you’re really serious about it, you’ll make each batch up fresh, grinding cardamom, cloves, cinnamon, pepper, ginger, and whatever other spices you use as needed. I know a few folks that do it that way, but not many. I’d recommend starting with a mix that you like.

The tea

In India, the tea leaf of choice is usually a rich black Indian tea like Assam. It’s brewed pretty strong so that you can taste the tea through all of the spice and milk and sweetener. That doesn’t mean you need to use an Assam, but it’s a good place to start.

The milk

Milk serves a definite purpose in masala chai. You can extract flavor from many spices much better in fats or oils than you can in water, as any chef will tell you. Steeping the spice blend in milk will result in a richer, more nuanced flavor than steeping it in water. In India, the milk of choice is typically water buffalo milk, which can be difficult to get hold of here in North America. The usual substitute is whole milk, although 1% or 2% is common with the more health-conscious crowd. Nonfat milk is rather pointless, as the fat is the main reason for using it.

The sweetener

Sugar. Some drink their masala chai unsweetened, but if there is sweetener, it will typically be sugar.

That said, when I’m making masala chai at home, I usually use honey or agave nectar.

The process

You’ll need a pan, a stove, and a strainer to do this. This is my recipe for making enough for you and a few friends. Adjust accordingly if you’re drinking it by yourself.

  1. Heat up a pint (16 oz) of milk in the pan, but do not bring to a boil!
  2. Add 1-1/2 tablespoons of masala spice mix and simmer for five minutes, stirring gently
  3. Bring a pint (16 oz) of water to a boil in a kettle or microwave
  4. Add the water to the pan along with 1-1/2 tablespoons of tea leaves
  5. Stir in 1 teaspoon of sugar or honey
  6. Allow to simmer for another five minutes, stirring occasionally
  7. Pour through strainer to remove leaves and spices, and serve immediately

Put out more sugar or other sweetener for your guests. That single teaspoon is a lot less than a traditionalist would use, but I prefer to let everyone choose their own level of sweetness.

For best results, enjoy with your favorite Indian foods. Masala chai does a wonderful job of cutting the spiciness of curries. You can also use your masala chai tea in your Indian cooking: see my post on Chai Rice.

NOTE: The resulting masala chai will not look like the latte in the picture above. To get that look, I frothed up some milk and placed the foam on the top of the cup, and then added a dash of cinnamon powder.

Making sweet tea on demand


If my tea bar was in Georgia, sweet tea wouldn’t be a problem for me. I would always have a pitcher or two sitting in the fridge. But here in Montana, the demand for sweet tea is pretty low. If I serve three or four glasses of sweet tea in a week, that’s a lot. Why is that a problem? Because properly-prepared sweet tea is made in advance. Ideally, it should sit overnight, but a few hours is probably okay. It will keep for a little while, but not indefinitely. If I make it by the pitcher, I’m going to end up throwing away most of it.

My goals are simple: I want it to taste like sweet tea (in the opinion of my Southern friends), and I have to be able to prepare it from scratch in about five minutes.

I’ve been fiddling with solutions to the problem, and I think I’ve come up with an acceptable solution. My method is based on my 20-ounce iced tea glasses, my ice machine (which makes very small cubes), and various other things specific to my specific setup. Obviously, you’ll need to tweak it a bit for your own use.

For sweetening iced teas (especially boba tea), I keep simple syrup on hand all of the time. We make it using equal quantities of boiling water and plain sugar, and then cool it down to room temperature. It’s much easier than trying to mix granulated sugar into cold tea.

First, I add a tablespoon of strong black tea to the infuser. I use our Irish Breakfast Tea, which is a blend of Assam and Tanzanian tea. The leaves are finely broken, which maximizes the surface area for steeping.

To the leaves, I add four tablespoons of simple syrup and about 10oz of boiling water. I suppose I could use some alternate method for sweetening the tea, but I have never heard a request for diet sweet tea. If it’s not real sweet tea with sugar, it’s just sweetened tea, I suppose.

While it is steeping, I fill the glass all the way to the brim with ice.

I steep the tea for five minutes. I would never steep a cup of Irish breakfast tea that long for myself, especially with that much leaf, because I’m a bit of a purist and I don’t add milk or sugar. Steeping that long makes plain tea very bitter. Using this much sugar, however, offsets that bitterness, and adding it to during the steep makes the tea taste different than if it’s added after the fact.

When the tea is poured over the ice, most of the ice will melt. Add a straw and you’re good to go.

Why I Use a Tea Timer


I’m not a tea snob, but … oh, who am I fooling? Of course I’m a tea snob. But that’s only because my favorite tea is objectively and fundamentally better than your favorite tea. And my favorite sports team could absolutely kick the snot out of your favorite sports team. But I digress…

I have physical tea timers, timers on my phone, timers on my iPad. I’m never without a tea timer.

I drink tea all day at work. Of course. “Work” is a tea bar and bookstore. I can’t read books all day, but I most certainly can (and do) drink tea. Whether I’m having my favorite tea or experimenting with something new, I time my brew. I do the same at home, in hotel rooms, and (quite discretely) in restaurants.

Why do I do this? Because my OCD requires me to prepare each tea precisely the same or I won’t enjoy it? Of course not! And, by the way, the acronym should be CDO, so it’s in alphabetical order like it ought to be. But I digress again…

If I don’t use a timer, there are two different ways I end up brewing my tea:

The impatient understeep

The tea is ready, right? That color looks about right. Man, that smells delicious. It must be ready by now. It feels like it’s been steeping all afternoon. That’s it. I can’t wait any longer. I’m drinking it now.

Hmmm. I wonder why this tea tastes so mild and watery?

The distracted oversteep

I have a couple more minutes until this tea is ready. I’ll run over and put that tin away. Why did nobody wash this infuser? I’d better put some more water on to boil. Oops, the phone is ringing. I’d better answer it.

(20 minutes later) Oh, my tea is probably ready. I wonder it’s so bitter and nasty?

By using a timer, I avoid both of these problems, although for the second problem it really needs to be a time that makes noise.

By timing tea for customers, I also assure that they get a consistent cup of tea every time they visit. In that case, being diligent about the amount of leaf, amount of water, steep time, and any other variables I can control means that our tea is shown off well, which encourages people to buy loose tea.

Tea + sweetener isn’t the same as sweet tea


Here’s a tip for my fellow Yankees: if a Southern friend asks for a cup of sweet tea, do not hand them a glass of iced tea and a couple of packets of sweetener. Sweet tea and sweetened tea are simply not the same thing.

They take their sweet tea quite seriously in Georgia. A decade ago, Georgia State Representative John Noel, along with four co-sponsors, introduced House Bill 819. The bill demanded that if a restaurant in Georgia served iced tea at all, it must serve sweet tea. The sponsors admitted that the bill was an April Fools Day joke, but that they were half-serious about it. The bill said:

(a) As used in this Code section, the term ‘sweet tea’ means iced tea which is sweetened with sugar at the time that it is brewed.

(b) Any food service establishment which served iced tea must serve sweet tea. Such an establishment may serve unsweetened tea but in such case must also serve sweet tea.

(c) Any person who violates this Code section shall be guilty of a misdemeanor of a high and aggravated nature.

There is no universal perfect glass of sweet tea any more than there’s a universal perfect cup of tea. There are, however, some simple rules you can follow to keep from embarrassing yourself in front of any guests you may have from Georgia.

Rule 1: Start with strong black tea. Even though sweet tea began as a green tea drink (more on that below), modern sweet tea is made with black tea steeped longer than most tea aficionados would approve.

Rule 2: Use plain white sugar, and lots of it. No artificial sweetener, no brown sugar, just good old-fashioned cane sugar.

Rule 3: The sugar goes in while the water is hot, preferably while the tea is brewing. Do not add the sugar after you chill the tea!

Rule 4: The tea needs to sit for a while in the fridge before serving. Overnight is good, but plan a few hours at least.

Rule 5: Additional ingredients like lemon and fresh mint leaves are a nice touch, but they are optional. Do not add mint or lemon without asking first. Serve it on the side.

So let’s back up a minute. Did I say above that sweet tea was originally made with green tea? Yes, indeed. The oldest know recipe for sweet tea comes from Housekeeping in Old Virginia by Marion Cabell Tyree, a cookbook first published in 1879, and it calls for green tea. In fact, the majority of sweet tea was made from green tea until World War II, when Americans disapproved of almost anything Japanese and switched to Indian (or Ceylon) black teas instead.

As any black tea drinker knows, the longer you let the tea steep, the stronger and more astringent it gets. For the most part, if you’re going to steep that tea longer than five minutes, you’ll be adding something to cut the bitterness. Personally, three minutes is plenty for me with most black teas. But with a Southern sweet tea, five minutes is a bare minimum. I’ve seen recipes calling for anything from seven minutes up to half an hour of steeping time.

Since the tea will be diluted with ice later, it’s traditional to use more tea leaf as well. Where I’d use a tablespoon of black tea leaves per pint of water for plain hot black tea, I use twice that much for sweet tea. An ounce of leaf per quart of water is not excessive. You can use teabags if you wish, but I think you get better results with loose whole leaf tea.

As per rule 2 above, don’t skimp on the sugar, either. About 3/8 of a cup of sugar per quart of water works well, but I know few Southern belles that would complain if you went up to 1/2 cup. For optimal results, dissolve the sugar completely in the water before steeping the tea in it, and make sure that water is boiling.

Once you’ve removed the tea leaves, put the pitcher in the fridge and let it chill down. For best results, it should be cold before you pour it over the ice to serve it.

The Perfect Cup of Tea part 2 (Royal Society of Chemistry)


RSC teacup

Last week, we took a look at the International Organization for Standards (ISO) and their standard for the perfect cup of tea (ISO 3103:1980). They are by no means the only organization out there that believes it knows what constitutes “perfect” when tea is concerned!

Today, we’ll look at Britain’s Royal Society of Chemistry, and a 2003 press release they issued called How to make a Perfect Cup of Tea (their capitalization, not mine!). You can download this document in PDF format from their website if you’d like.

I’m sure the RSoC is a wonderful organization. Their self-description on the press release sounds downright wonderful.

“The Royal Society of Chemistry is the leading organisation in Europe for advancing the chemical sciences. Supported by a network of 45,000 members worldwide and an internationally acclaimed publishing business, our activities span education and training, conferences and science policy, and the promotion of the chemical sciences to the public.”

Were I a chemist in Great Britain (or possibly even here in the U.S.), I would definitely want to join this society. But a quick perusal of that paragraph above fails to reveal anything about their expertise in tea. Perhaps it’s just that they are British. That must be it.

The document begins, logically enough, with a list of ingredients and a list of implements. This raised my eyebrows immediately.

“Ingredients: Loose-leaf Assam tea; soft water; fresh, chilled milk; white sugar.”

I love Assam tea as much as the next guy, but is using Assam really a prerequisite for preparing the perfect cup of tea? Can a white-tip Bai Hao oolong not be perfect?

And I’m going to let a bit of my prejudice show here: I’m no tea Nazi, and I’m happy to let you prepare your tea your own way. I do, however, think that if a cup of tea is perfect there is no need to adulterate it with milk and sugar.

“Implements: Kettle; ceramic tea-pot; large ceramic mug; fine mesh tea strainer; tea spoon, microwave oven.”

Oh, my! One of the implements required for preparing the perfect cup of tea is a microwave oven? Please tell me that my friend Angela from London isn’t reading this. It would set her poor heart aflutter. They’re only using the microwave to warm up the cup, but still!

The instructions follow all of the standard British rules for making a cup of black tea (I’m sure George Orwell would approve): pre-warm the cup, take the pot to the kettle, pour the milk in the cup before the tea, and so forth. I will give them kudos for this little gem:

“Drink at between 60-65 degrees Centigrade to avoid vulgar slurping which results from trying to drink tea at too high a temperature.”

It’s the next paragraph, though, that stopped me in my tracks.

Personal chemistry: to gain optimum ambience for enjoyment of tea aim to achieve a seated drinking position in a favoured home spot where quietness and calm will elevate the moment to a special dimension. For best results carry a heavy bag of shopping – or walk the dog – in cold, driving rain for at least half an hour beforehand. This will make the tea taste out of this world.”

I simply don’t know what else to say. I’m going to go prepare myself an imperfect cup of tea and ponder this for a while.

Making the perfect cup better?


What timely news! Last week, I wrote about standards for preparing the perfect cup of tea, including ISO 3103:1980 and the British standard BS-6008. A couple of days ago, Marc Abrahams wrote an article for the Guardian entitled “The correct way to make a cuppa is being reviewed,” which says that the British Standards Institution is reviewing BS-6008 and several related standards, including the ones for black tea (BS-3720), green tea (BS-11287), and instant tea (BS-7390). Is there actually such a thing as a perfect cup of instant tea? I suppose that’s a question for another blog post, but I suspect the answer will be a resounding no.

I believe that standards organizations perform an important service. We may laugh about silly standards from time to time — Marc Abrahams does quite a bit of that as editor of the Annals of Improbable Research and organizer of the Ig Nobel prize — but where would we be if people couldn’t agree on standard measurements or file formats? I served on the CEA (Consumer Electronics Association) committee that defined the standards for television closed captioning and saw how important it is for broadcasters and TV manufacturers to agree on how things work.

Sometimes, however, you just have to laugh. BS-6008 is being reviewed in time for World Standards Day on Monday, October 14, 2013. With a name like “World Standards Day,” you’d assume that we’ll all be celebrating it on a, well, “standard” day, right? As my father taught me, never assume. In 2013, the US will hold World Standards Day on Thursday, October 3, and Canada will wait for Wednesday, October 16.

And people wonder why we can’t agree on how to make a cup of tea.

UPDATE!

BS 6008:1980, “Method for preparation of a liquor of tea for use in sensory tests,” was officially withdrawn on 18 Sep 2023. I guess they listened!

The Perfect Cup of Tea part 1 (ISO 3103:1980)


ISO teacup

Everybody wants to brew the perfect cup of tea. Well, except those silly coffee drinkers, but we usually ignore them on our tea blogs, don’t we?

I’ve made it clear on this blog before that I’m not a big fan of tea Nazis, nor do I necessarily agree with folks like George Orwell about what constitutes a “nice cup of tea.” There are many, however, that believe the perfect cup is not subjective and is not open to debate.

Some organizations that feel they have the secret well in hand have released official documents describing the process, although I suppose that means it’s not a secret anymore. I’ve recently looked over a couple of those documents that I’d like to share. Today, we’ll look at a lovely document called ISO 3103:1980.

ISO 3103: Tea — Preparation of liquor for use in sensory tests

The International Organization for Standardization (ISO) has developed standards for everything from electronics to language and currency codes to quality control management. They also have a food safety management group that has taken it upon themselves to set the standard for preparing a cup of tea.

The standard itself (ISO 3103:1980) is available in the U.S. for the low, low price of $45.00 (less for members) from ANSI, the American ISO member (buy it here). The official description is

“The method consists in extracting of soluble substances in dried tea leaf, containing in a porcelain or earthenware pot, by means of freshly boiling water, pouring of the liquor into a white porcelain or earthenware bowl, examination of the organoleptic properties of the infused leaf, and of the liquor with or without milk or both.”

(I have to confess, word geek that I am, that I had to look up the word “organoleptic.” I will definitely be using this word in the future!)

For those who don’t wish to pony up forty-five bucks for the official standards document, there is a summary on Wikipedia. In keeping with their Creative Commons Attribution-ShareAlike License, I shall copy the details here and save you the trouble of clicking on the link. I’m changing their bullet points to a numbered list for easy reference. These numbers don’t appear in their document.

  1. The pot should be white porcelain or glazed earthenware and have a partly serrated edge. It should have a lid that fits loosely inside the pot.
  2. If a large pot is used, it should hold a maximum of 310 ml (±8 ml) and must weigh 200 g (±10 g).
  3. If a small pot is used, it should hold a maximum of 150 ml (±4 ml) and must weigh 118 g (±10 g).
  4. 2 grams of tea (measured to ±2% accuracy) per 100 ml boiling water is placed into the pot.
  5. Freshly boiling water is poured into the pot to within 4–6 mm of the brim. Allow 20 seconds for water to cool.
  6. The water should be similar to the drinking water where the tea will be consumed
  7. Brewing time is six minutes.
  8. The brewed tea is then poured into a white porcelain or glazed earthenware bowl.
  9. If a large bowl is used, it must have a capacity of 380 ml and weigh 200 g (±20 g)
  10. If a small bowl is used, it must have a capacity of 200 ml and weigh 105 g (±20 g)
  11. If the test involves milk, then it is added before pouring the infused tea.
  12. Milk added after the pouring of tea is best tasted when the liquid is between 65 – 80 °C.
  13. 5 ml of milk for the large bowl, or 2.5 ml for the small bowl, is used.

Clearly, this standard is designed for comparative testing of tea, not for consumption. In my humble opinion, this standard would ruin the majority of the teas that I drink. The water temperature (paragraph 5) would make a bitter mess out of most white and green teas, and the steep time (paragraph 7) would destroy most of the black and pu-erh teas I drink (and the oolongs and greens, for that matter).

It surprises me not in the slightest that British version of this work (called, appropriately enough, BS-6008) received the Ig Nobel Prize in 1999.

In part 2 of this series, we’ll take a peek at what the Royal Society of Chemistry has to say.

Active vs. Passive Tea Consumption


There’s a big difference between the way tea is usually served in U.S. tea shops, and the way it’s served in Asia. I’ve been trying for a while to come up with the right words to describe it, and my friend Kory did the job for me last week.

Kory was sitting at my tea bar, trying to decide what he wanted as I was preparing myself some wild shu pu-erh in a gaiwan. I offered him a taste, and he said he’d give it a try. He watched as I went through the ritual and filled a small cup for him. He tasted it and said, “I’m looking for something more passive.”

My favorite blue flower gaiwan.

My first thought was that he was referring to the process of preparing the tea (he wasn’t, but more on that later), and I realized that he’d just given me the words I was looking for. American/European tea drinking is passive, while Asian tea drinking is more active.

When my daughter and I went to Bellingham and Seattle last month, two of the tea shops we visited exemplified this perfectly.

The first was an English-style tea house called Abbey Garden Tea Room. We sat at a table and ordered our food and tea. They steeped the tea in the kitchen, and brought us teapots (with the tea leaves removed), tea cozies, and cups. All that was required of us was to pour the tea in a cup and drink it. The pots were large enough that we didn’t need refills during our meal.

The second was a Chinese tea house called Vital Tea Leaf. We sat at the counter and talked to the tea expert on staff (her name was Fang). She asked what kind of tea we liked, and set up a gongfu tray in front of us with an assortment of teaware. For each tea, we smelled the dry leaves and the wet leaves, and watched as she prepared a few ounces of tea in the gaiwan, gently agitating the leaves and fanning the aroma toward us.

The Abbey Garden experience was passive tea drinking. We picked tea we liked, and it became secondary to the rest of our lunch. We focused on the food and chatting with each other. With the larger British-style cups, we only had to refill a few times during the meal. At most American-style tea houses, those cups would have been even bigger — probably 12 to 16 ounces, and there would have been no refills required.

The Vital Tea Leaf experience was active tea drinking. There were no distractions, and we only got a couple of ounces of tea at a time. We were engaged in the process the entire time, and it was all about the tea.

Most of the time, passive tea drinking is fine with me. I am sipping on a large mug of houjicha as I write this, and although I’m enjoying it, the tea in my mug isn’t my primary concern at the moment.

But there’s a lot to be said for the active tea drinking experience. Watching the tea steep (experiencing the “agony of the leaf”), comparing the changes from the first infusion to the next, smelling, sipping, tasting, and concentrating on the tea you drink. I think after I press the “post” button for this article, I shall pull out the gongfu tray and gaiwan and actively drink some tea!

Sidebar: What Kory really meant

In my opening paragraphs, I spoke about my friend who gave me the idea for the terms active and passive, and mentioned that the whole subject of this article isn’t really what he meant.

What he was trying to say is that the taste of the tea itself can be active vs. passive. For you beer drinkers out there, here’s a comparison. You’ve gotten together with a bunch of friends to watch the game on TV. Your friend hands you a glass of beer just as there’s some great action going on. You drink the whole beer without having any idea what it was (it was probably Bud Light). There just wasn’t enough taste to get your attention. That’s a passive drink.

On the other hand, if he had handed you an oatmeal stout, a lambic, or a double IPA, you probably would have stopped what you were doing to focus on the beer. “Wow. What is that?” You would have smelled and sipped, savoring the beer and missing the touchdown that put your team in the lead. That’s an active drink.

The wild shu pu-erh I spoke of at the beginning of the article is most definitely active. There’s a lot going on in that tea. It’s rich, deep, and complex, with flavors and aromas that are very hard for me to identify. Kory was interested in a good, but passive tea. Perhaps a Keemun black. You taste it, notice it, and then drink the rest of the cup without paying attention.

Okay, Keemun tea lovers. I’ve painted the target on my back. I await your wrath.
