The Rooibos of South Africa: Stop 7 on the World Tea Tasting Tour
If you’re looking for a drink with all the health benefits of tea, a similarly great taste, but no caffeine, look to South Africa! Rooibos is made from the South African red bush (Aspalathus linearis). Using rooibos instead of tea is a great way to enjoy a caffeine-free hot (or iced) drink without using any chemical decaffeination process. Rooibos is full of antioxidants, Vitamins C and E, iron, zinc, potassium, and calcium. It is naturally sweet without adding sugar.
Rooibos grows only in the Western Cape of South Africa, and a similar plant called honeybush (the Cyclopia plant) grows in the Eastern Cape. Its flowers smell of honey, hence the name. The taste of honeybush is similar to rooibos, though perhaps a bit sweeter. Like rooibos, honeybush is naturally free of caffeine and tannins; perfect for a late-evening drink.
The teas we tasted were:
- Red rooibos (organic)
- Green rooibos (organic)
- Honeybush (organic)
- Jamaica red rooibos (organic, fair trade)
- Bluebeary relaxation (organic, fair trade)
- Iced rooibos
- Cape Town Fog (a vanilla rooibos latte!)
South Africa, as the name implies, sits at the very southern tip of the African continent. It completely surrounds a small country called Lesotho. South Africa covers 471,443 square miles (about three times the size of Montana) and has a population of 51,770,000 (a bit more than Spain). Despite wide open spaces in the middle of the country, the large cities make it overall densely populated.
The country has the largest economy in Africa, yet about 1/4 of the population is unemployed and living on the equivalent of US $1.25 per day.
Red rooibos
Rooibos isn’t a huge part of the South African economy. It does, however, employ about 5,000 people and generates a total annual revenue of around US $70 million, which is nothing to sneeze at. The plant is native to South Africa’s Western Cape, and the country produces about 24,000,000 pounds of rooibos per year.
The name “rooibos” is from the Dutch word “rooibosch” meaning “red bush.” The spelling was altered to “rooibos” when it was adopted into Afrikaans. In the U.S., it’s pronounced many different ways but most often some variant of ROY-boss or ROO-ee-bose.
I’ve written quite a bit about red rooibos in several posts — and about the copyright issues — so I won’t repeat it all here. Rooibos is also great as an ingredient in cooking: see my African Rooibos Hummus recipe for an example.
Green rooibos
Green rooibos isn’t oxidized, so it has a flavor profile closer to a green tea than a black tea. Again, I’ve written a lot about it, so I’ll just link to the old post.
Honeybush
Honeybush isn’t one single species of plant like rooibos. The name applies to a couple of dozen species of plants in the Cyclopia genus, of which four or five are used widely to make herbal teas. Honeybush grows primarily in Africa’s Eastern Cape, and isn’t nearly as well-known as rooibos.
It got its name from its honey-like aroma, but it also has a sweeter flavor than rooibos. It can be steeped a long time without bitterness, but I generally prefer about three minutes of steep time in boiling water.
Jamaica Red Rooibos
I decided to bring out a couple of flavored rooibos blends for the tasting as well. The first is Jamaica Red Rooibos, a Rishi blend. It has an extremely complex melange of flavors and aromas, and is not only a good drink, but fun to cook with as well (see my “Spicing up couscous” post).
Jamaica Red Rooibos is named for the Jamaica flower, a variety of hibiscus. The extensive ingredient list includes rooibos, hibiscus, schizandra berries, lemongrass, rosehips, licorice root, orange peel, passion fruit & mango flavor, essential orange, tangerine & clove oils
BlueBeary Relaxation
BlueBeary Relaxation one of the blends in our Yellowstone Wildlife Sanctuary fundraiser series (the spelling “BlueBeary” comes from the name of one of the bears at the Sanctuary). It’s an intensely blueberry experience that’s become a bedtime favorite of mine. It’s like drinking a blueberry muffin!
Iced rooibos
To make a really good cup of iced rooibos, prepare the hot infusion with about double the leaf you’d use normally, because pouring it over the ice will dilute it. Both green and red rooibos make great iced tea. I prefer both styles unadulterated, but many people drink iced red rooibos with sugar or honey.
Cape Town Fog
This South African take on the “London Fog” is a great caffeine-free latte. To prepare it, you’ll want to preheat the milk almost to boiling. If you have a frother of some kind, use it — aerating the milk improves the taste. Steep the red rooibos good and strong, and add a bit of vanilla syrup or extract. We use an aged vanilla extract for ours. Mix it all up, put a dab of foam on top if you frothed the milk, and optionally top with a light shake of cinnamon.
This was the seventh stop on our World Tea Tasting Tour, in which we explore the tea of China, India, Japan, Taiwan, England, South Africa, Kenya, and Argentina. Each class costs $5.00, which includes the tea tasting itself and a $5.00 off coupon that can be used that night for any tea, teaware, or tea-related books that we sell.

Rooibos: The African Red Bush
How have I been at this blog for so long without writing about rooibos? Oh, I know this blog is about tea, and I did write a post about green rooibos last year, but I haven’t covered straight red rooibos yet.
Rooibos comes from a bush called Aspalathus linearis, which grows in the west cape of South Africa. The name “rooibos” is from the Dutch word “rooibosch” meaning “red bush.” The spelling was altered to “rooibos” when it was adopted into Afrikaans.

Rooibos is also often called “red tea,” but most tea professionals shy away from that name for several reasons:
- The term “red tea” is used by the Chinese to refer to what we call “black tea.” No sense having two different drinks with the same name.
- Rooibos isn’t tea, since it doesn’t come from the Camellia sinensis plant. Instead, it is a tisane or herbal infusion.
- Rooibos only has that rich red color when it’s processed like a black tea. Green rooibos is more of a golden honey-colored infusion.
Rooibos is a tasty drink that is also good for cooking. Hopefully, I’ll have a chance sometime soon to write a review soon of the cookbook A Touch of Rooibos. I have been looking through it lately and it’s filled with interesting ideas. Generally, when used for cooking, the rooibos is steeped for quite a while and then reduced to a thick syrupy consistency. Unlike black tea, it can be steeped for ten minutes or more without becoming unpalatable and bitter.
Unlike “real” tea, which all has caffeine, rooibos is naturally caffeine-free. Since the flavor is similar to a mild black tea, this makes it a favorite bedtime beverage for many tea drinkers. Rooibos is also high in antioxidants.
Herbalists make many claims about the health properties of the rooibos tisanes. The Web site for the South African Rooibos Council (SARC), in fact, has very little information that isn’t in some way tied back to health claims. There are more and more studies being done, but available data are lacking in specifics (in my opinion, anyway) so I’m not going to quote any of those there. Feel free to check SARC’s site for lots of studies.
I don’t mean to imply that rooibos is only about the health benefits. It is, in fact, a very tasty drink. Most rooibos drinkers in the U.S. enjoy it straight or with a bit of sweetener (honey or sugar). In South Africa, it is commonly served with a bit of milk or lemon as well as honey. A group funded by SARC and Stellenbosch University has recently developed a “sensory wheel” for rooibos, describing both the desirable and undesirable aspects of flavor and mouthfeel. If you are interested in more information, click on the wheel below.
Rooibos Sensory Wheel as described in the article “Sensory characterization of rooibos tea and the development of a rooibos sensory wheel and lexicon,” available on Science Direct. Click the wheel above to view the article — there is a charge for the full text version.
Also, there is an article you can download in PDF format (click the thumbnail to the right to download) that describes the sensory wheel and the process used to create it.
Compared to tea, rooibos is a pretty small market. South Africa’s annual rooibos production is about 12,000 tons. That output is about equivalent to annual tea production of the Darjeeling region of India, or about a tenth of the tea production of Japan (the 8th largest tea producing country). Nonetheless, rooibos is important to South Africa, employing about 5,000 people and generating about $70 million in revenues.
The leaves of the rooibos bush are more like needles than the broad leaves of a tea plant. To produce red rooibos, the leaves are harvested, crushed, and oxidized using a process based on the one used in making Chinese black tea. Typically, the leaves are sprayed with water and allowed to oxidize for about 12 hours before being spread out in the sun to dry.
Green rooibos, as the name implies, is unoxidized or very lightly oxidized, and is processed more like a green tea.
For more information about the rooibos industry, I recommend the article Disputing a Name, Developing a Geographical Indication, from the World Intellectual Property Organization.
Tea and caffeine part III: Decaf and low-caf alternatives
The loneliest molecule?
This article is the second of a three-part series.
Part I: What is caffeine?
Part II: Exploding the myths
Part III: Decaf and low-caf alternatives
So you’ve decided you like tea, but you really don’t want (or can’t have) the caffeine. What are your alternatives?
Well, first there’s decaf tea. As Part I of this series explained, decaffeination processes don’t remove 100% of the caffeine, so this is a reasonable alternative if you want less caffeine, but not if you want none at all. There’s another problem with switching to decaf: the selection of high-quality decaffeinated tea is — let’s just say, limited.
It’s easy to find a decaf Earl Grey or a decaf version of your basic Lipton-in-a-bag. But if your tastes run more to sheng pu-erh, sencha, dragonwell, lapsang souchong, silver needle, Iron Goddess of Mercy, or organic first-flush Darjeeling, you have a problem.
You can try the “wash” home-decaffeination method, but I explained a couple of days ago why that process is overrated. You’re likely to be able to remove 20% or so of the caffeine that way, but that’s about it.
Another alternative is simply to brew weaker tea and/or use more infusions. Let’s do the math for an example. Assume you’re a big fan of an oolong that contains 80 mg of caffeine in a tablespoon of leaves, and you drink four cups of tea per day.
If you use a fresh tablespoon of leaves for each cup, and you steep it for three minutes, you will be extracting about 42% of the caffeine in each cup, which equals 34 mg per cup, or a total of 136 mg of caffeine for the day. If you shorten your steep time to two minutes, the extraction level drops to about 33% (total of 106 mg). Alternatively, you could use the leaves twice each time, so you’re extracting about 63% of the caffeine, but using a total of half as many leaves (total of 101 mg). Or, if you don’t mind significantly weaker tea, just use 1-1/2 teaspoons of leaves instead of a full tablespoon. Half the leaves means half the caffeine (total of 68 mg).
No caffeine at all
If you look through the selection of teas in a health-food store, you’ll notice that most of them have no tea at all, and the vast majority of those non-tea drinks have no caffeine. The problem is that chamomile for a tea drinker is like Scotch to a wine drinker; it’s just not the same.
There are a couple of beverages, however, that are somewhat similar to tea. Both come from South Africa and both are naturally caffeine-free.
The rooibos plant (Aspalathus linearis)
Rooibos is often called “red bush” in the United States because the way it’s usually prepared leaves a deep red infusion. Typically, rooibos is oxidized (not fermented) like a black tea. It can also be prepared more like a green tea. I blogged about green rooibos last August if you’d like to know more about it.
North American news shows, along with people like Oprah and Dr. Oz, have been singing the praises of rooibos lately, bringing it more into the mainstream awareness. It is very high in antioxidants and much lower in tannins than a black tea. Unfortunately, there isn’t a lot of independent research published about it yet, so many of the claims can’t really be backed up. The one that can be backed is that it has no caffeine and it tastes kind of like black tea (green rooibos is a bit grassy with malty undertones, more like a Japanese steamed green tea with a touch of black Assam).
The honeybush plant has a number of distinct species. Pictured here is Cyclopia meyeriana.
Honeybush, like rooibos, grows only in South Africa. Also like rooibos, it is naturally caffeine-free and can be prepared either as a red or a green “tea.” When blooming, the flowers smell like honey, and honeybush tends to be somewhat sweeter than rooibos. Honeybush isn’t nearly as well-known as rooibos in the U.S., and the green version is very hard to find. I’ve found that if you want a flavored honeybush, citrus complements it very well. My “Hammer & Cremesickle Red” is the most popular honeybush blend in our tea bar (here is a blog post about it, and you can find it on the store website here).
A blended approach
If you like the idea of reducing your caffeine intake, but you don’t like the idea of a weaker tea (as I described above) or switching to rooibos or honeybush, you might want to consider blending. If you mix your tea half-and-half with something containing no caffeine, then you can still brew a strong drink, but get only half the caffeine from it. Combine that with the other tricks, like taking two infusions, and you can cut it even farther.
