What Is Rooibos? The Red Bush Tea You'll Want Every Evening
Pull up a chair, dear. I want to tell you about rooibos, or as we say in French, the little red bush tea that somehow slipped past most Americans for decades before landing squarely on every herbal tea shelf in the country. I've been drinking it for nearly thirty years now, and I still pour myself a cup most evenings when the day finally slows down.
If you've seen it in the store and wondered what exactly you're looking at, well, you're in good company. It looks like black tea in the cup, tastes nothing like black tea in the mouth, and comes from a plant that isn't tea at all. Let me clear all of that up for you.
⭐ Key takeaways
- Rooibos comes from a single shrub grown only in the Cederberg mountains of South Africa.
- It is completely caffeine-free, naturally sweet, and low in tannins.
- There are two types: fermented red rooibos and unfermented green rooibos, and they taste very different.
- It brews best with boiling water, for at least 5 minutes. This is one tea that actually likes the wait.
- It pairs beautifully with milk, honey, and spices, or completely on its own.
Where Rooibos Actually Comes From
Rooibos (pronounced ROY-boss, rhymes with "voice") grows in exactly one place on earth: the Cederberg mountain range, about 200 miles north of Cape Town in South Africa. The plant is Aspalathus linearis, a fine-needled shrub from the legume family that thrives in the region's sandy, acidic soil and dry mountain air. Try to grow it anywhere else, and it simply refuses. Farmers in other countries have attempted it for decades. Nothing.
The Khoisan people, the indigenous inhabitants of the region, harvested and brewed the plant long before any European set foot in the Cape. They would cut the branches, bruise the needles with a hammer or stone, leave them to ferment in the sun, and drink the red brew that resulted. The knowledge was passed down through generations, and for a long time it stayed firmly local.
It was a Russian botanist named Benjamin Ginsberg who brought rooibos to a wider market in the early 1900s. He noticed the Khoisan drinking it, recognized it as something worth trading, and started selling it commercially. By the 1930s, a handful of South African farms had begun cultivating it in earnest. By the end of the century, it was exported around the world.
💡 Did you know?
The word "rooibos" is Afrikaans for "red bush." But here's the twist: when the plant is still growing on the hillside, its needles are green. The red color only appears after the leaves are harvested, bruised, and left to ferment in the open air. It's the same basic chemistry that turns green tea black, just with a completely different plant and a very different result.
Red Rooibos vs. Green Rooibos: What's the Difference?
Most people only know red rooibos. That's the fermented version, and it's what you'll find on nearly every supermarket shelf in America. The needles are harvested, bruised, piled up, and left to oxidize in the South African sun for several hours. The result is that familiar warm red-brown color, a mellow sweetness, and a round, slightly earthy flavor.
Green rooibos, though, is a different story. It's processed more like Japanese green tea: cut, then immediately dried to stop oxidation before it begins. The flavor is lighter, slightly grassy, with a more delicate sweetness and a gentle nuttiness. It's less common, harder to find outside specialty shops, and honestly it surprised me the first time I tried it. I wasn't expecting something that clean from a South African bush.
| Criterion | Red Rooibos (Fermented) | Green Rooibos (Unfermented) |
|---|---|---|
| Color in cup | Deep amber to red-brown | Pale gold to light amber |
| Flavor profile | Sweet, earthy, vanilla-like, full-bodied | Grassy, light, nutty, more delicate |
| Tannin level | Very low | Practically none |
| Caffeine | None | None |
| Availability | Widely available | Specialty shops only |
| Best with | Milk, honey, spices, evening hours | Plain, or a thin slice of lemon |
What Does Rooibos Taste Like?
This is the question people ask me most. And the honest answer is: nothing else quite like it. The closest I can describe it is a warm, naturally sweet cup with a gentle earthiness. There's a hint of vanilla sometimes, a whisper of something woody, and almost none of that drying sensation you get from black tea when you brew it too long. That bitterness you know from an over-steeped black tea? Rooibos simply doesn't do that.
It has very low tannins. Tannins are the compounds in tea that give it astringency, that slight grip on the sides of your tongue. Black tea has plenty, which is exactly why it goes well with milk. Rooibos has almost none, which means it's smooth even without milk, even brewed for ten minutes. It's forgiving that way, and I appreciate that in an evening cup when I don't feel like watching a timer.
The natural sweetness is real, not added. You don't need sugar with a good rooibos. A bit of honey if you like, a splash of warm milk if you want something cozy, a cinnamon stick in winter. Or nothing at all. It holds up beautifully on its own.
How to Brew Rooibos Properly
Here's where rooibos is wonderfully different from most teas: it actually wants boiling water. Full 212°F (100°C). No cooling, no waiting. Pour the boiling water straight over your leaves or bag and let it sit. Most teas would turn harsh if you did that, but rooibos is made for it.
Steeping time: give it room to breathe
The minimum I'd suggest is 5 minutes. Seven is better. Some people steep for 10 and find it even richer. There's no bitterness waiting to ambush you at the eight-minute mark, so relax. If you forget your cup while you're answering the phone, it'll be fine when you come back. That's the kind of tea rooibos is.
Loose leaf vs. tea bags
Both work. Loose leaf rooibos tends to have more of that fresh, slightly floral quality, and you can experiment with how much you use. I start with about one rounded teaspoon per cup (roughly 8 ounces of water). Tea bags are perfectly decent though. Rooibos is one of the few herbals where the bags don't disappoint me too badly. Back in my day we just called that an infusion, sweetheart, and a good one it was.
If you're using loose leaf, a proper infuser makes the process effortless. Nothing fancy required. A fine-mesh ball or basket keeps the needles in check and makes cleanup quick. You can use the same leaves for a second steep too, though the second cup will be lighter and milder.
The rooibos latte, for cold evenings
Brew a strong cup, about 1.5 teaspoons per 6 ounces of water, steep for 7 full minutes. Then top with warmed milk, whole milk ideally, and a little honey. Some people add a pinch of cardamom. It sounds fussy but it takes three minutes and it is one of the coziest things you can put in a mug on a November evening. No espresso machine required. No fancy anything.
Rooibos at Different Times of Day
This is the part I love about rooibos, and honestly it's why I keep coming back to it after all these years. There is no wrong time of day. Morning cup with your toast? Fine. Afternoon when the two o'clock slump hits? Perfect. Late evening when anything caffeinated would keep you up until 3 a.m.? This is where rooibos really earns its place on the shelf.
Caffeine-free red bush tea is genuinely, completely caffeine-free. Not in the way that some things are "practically caffeine-free." Rooibos is not a true tea at all. It comes from a different plant family entirely, one that produces no caffeine whatsoever. You could drink six cups before bed and sleep like a rock. I know because I have.
This makes it useful in ways that most teas aren't. Children can drink it. People who've given up coffee and miss having something warm and substantial in their hands love it. Anyone sensitive to caffeine but still wanting the ritual of a proper cup: this is your tea, honey.
"Rooibos is what you drink when you want the comfort of tea without the consequences."

The Art of Serving Rooibos: Traditions and Pairings
In South Africa, rooibos is often served the way the British drink tea: with milk and sugar, sometimes with a rusk, which is a dry twice-baked biscuit made for dunking. It's a very homey tradition. People drink it at the kitchen table, after work, with family. There's nothing formal about it.
Cold-brew rooibos in summer
Here's something I discovered completely by accident about fifteen years ago when I left a jug of steeped rooibos on the counter and forgot about it. Let it cool, pour over ice, add a slice of orange or a sprig of mint. The natural sweetness comes forward differently when it's cold. It becomes almost like a fruit infusion. Now I make a full pitcher every summer and keep it in the fridge. My grandchildren drink it by the glass and never notice it isn't juice.
Rooibos chai
You can use rooibos as the base for a caffeine-free chai that is genuinely good. Simmer rooibos with whole milk, a cinnamon stick, a few cardamom pods cracked open, two or three cloves, and a slice of fresh ginger. Let it go for 8 to 10 minutes. Strain, sweeten with a little honey or raw sugar. It's warming in a way that goes deep.
What food goes with rooibos
Because it's sweet and low in tannins, rooibos won't clash with food the way a strong black tea can. It pairs naturally with:
- Vanilla-based desserts (cakes, custards, rice pudding)
- Dried fruit and nuts (think an afternoon snack board)
- Mild cheeses
- Chocolate, dark or milk (the earthiness plays well against cocoa)
- Citrus: a squeeze of orange in the cup or a slice on the saucer
What I'd avoid: anything very spicy or sharp. The sweetness of rooibos gets a little confused next to big heat or heavy vinegar flavors. It's a peaceful tea. Give it peaceful company.
How to Choose Good Rooibos (and What to Skip)
I'll be straight with you here, because not all rooibos is created equal and some of what you'll find in the supermarket has been sitting on a shelf long enough to taste like dried cardboard.
What to look for
Good loose leaf rooibos should smell warm and slightly sweet when you open the bag. There should be some needle-length variety in the mix, not all powder. A slightly earthy, almost caramel-like scent is a good sign. If it smells like nothing, it probably is nothing. Old rooibos loses its character before it loses its color, so a bright red-orange color alone means very little.
Organic certification matters a bit more with rooibos than with some other teas, not because conventional is necessarily dangerous, but because the Cederberg region has historically used very few pesticides anyway and the organic versions tend to come from smaller farms with more careful processing. Worth the small price difference when you find it.
What to skip
Flavored rooibos blends. Now, I know this is a matter of personal taste and I won't argue with you if you love a strawberry-vanilla rooibos. But between you and me, many of those blends use low-grade rooibos as a base and rely on artificial flavoring to cover what's missing. Try a plain, unflavored rooibos first. If you like it, you'll know what you're tasting when the flavored versions come along.
Also skip anything sold in single-serve capsules for pod machines. I'm just not convinced by tea capsules in general, and rooibos in a pod is a waste of a beautiful tea. The pressure, the pre-ground consistency, the sealed plastic: none of it suits a slow-brewing herbal that wants space and time.
💡 Did you know?
The Cederberg Wilderness Area, where rooibos grows wild and where most farmed rooibos originates, is a UNESCO World Heritage Site. The fynbos biome there, a unique shrubland of extraordinary plant diversity, is found nowhere else on earth. Rooibos isn't just a tea with a nice story. It comes from one of the most botanically remarkable places on the planet.
Storing Rooibos at Home
Rooibos stores remarkably well compared to green or white teas, which are fragile things that fade within months. A well-sealed container kept away from light and moisture will keep rooibos in good shape for two years or even a little longer. It doesn't oxidize further once it's processed, and the aromatics are quite stable.
That said, treat it with some care. Air is the enemy: once you open a bag, move it into an airtight container. Metal or ceramic tins work beautifully. Keep it away from strong-smelling things in your pantry, because rooibos will pick up neighboring odors quietly, and coffee is the main culprit I'd warn you about. Your rooibos and your ground coffee should not share a shelf.
For loose leaf rooibos specifically, an airtight bamboo tea canister keeps things fresh and looks a lot better on your counter than a folded-over plastic bag. That's just practical wisdom from someone who has had the same shelf for twenty years. You might also appreciate a proper handcrafted wooden tea box if you're starting to accumulate a few different teas worth protecting.
Rooibos for the Whole Family
One of the things I genuinely love about rooibos is who can drink it. This is not a tea you have to ration or think carefully about before serving. Completely caffeine-free means it works for children, it works for elderly family members who've been told to watch their caffeine, it works for anyone who is pregnant and misses having a warming cup in the afternoon. That covers a very wide table.
My own grandchildren grew up drinking cold-brew rooibos in the summer as if it were lemonade. They had no idea it was tea. Now that they're old enough to know, they still drink it. That tells me something.
If you're serving a group with different tolerances and preferences, a pot of rooibos on the table is one of the most peaceable things you can put out. Nobody gets wound up, nobody has to refuse, and everyone gets something warm and delicious. I've served it at family gatherings for years for exactly that reason.
The Everyday Ritual: Why Rooibos Stays on Granny's Shelf
I want to leave you with something honest here. Rooibos is not the most complex tea in my collection. It doesn't have the terroir drama of a first-flush Darjeeling or the ceremony weight of a bowl of matcha. But that's not what it's for.
Rooibos is the tea that waits for you at the end of the day. The one that doesn't require anything from you. You don't have to watch the temperature, you don't have to count the seconds, you don't have to do anything except give it a few minutes and then sit down. It rewards the slow pace of an evening. It's warm and uncomplicated and genuinely pleasant, and some days that's exactly what you need.
I keep it next to the kettle because it earns that spot. If you haven't tried a proper cup yet, I'd start with a plain loose leaf red rooibos, boiling water, seven minutes, no milk, no sugar. Just to know what it actually is. Everything else you add or subtract from there is up to you. And if you'd like good company for your loose leaf teas, take a look at our stainless steel tea infusers: a fine-mesh strainer makes all the difference with those small needles. You'll also find our full teapot collection ready when you're looking for the right vessel to make this a proper ritual.
Frequently asked questions
What is rooibos tea?+
Rooibos is a naturally caffeine-free herbal infusion made from the needle-like leaves of Aspalathus linearis, a shrub that grows only in the Cederberg mountains of South Africa. It is not a true tea (true teas come from the Camellia sinensis plant) but is commonly called tea because of how it is brewed and enjoyed. It has a warm, naturally sweet flavor with earthy and faintly vanilla-like qualities, no bitterness, and very low tannins. The word "rooibos" is Afrikaans for "red bush."
How long should you steep rooibos?+
Steep rooibos for at least 5 minutes, and ideally 7 minutes, in fully boiling water (212°F / 100°C). Unlike black or green tea, rooibos does not turn bitter with a long steep. Ten minutes gives you a richer, fuller cup and that is perfectly fine. If you forget it on the counter for a few extra minutes, do not worry. Rooibos is one of the most forgiving teas you will ever brew.
Can you re-steep rooibos?+
Yes, you can re-steep rooibos, especially loose leaf. The second steep will be noticeably lighter and milder than the first, but it is still pleasant. Use the same boiling water temperature and give the second brew a full 7 to 8 minutes to draw out what remains. I would not push to a third steep: by then there is really very little left, and you deserve a proper cup.
Is rooibos a real tea?+
No, technically it isn't. True tea comes from the Camellia sinensis plant, which gives us black, green, white, and oolong tea. Rooibos comes from a completely different plant, Aspalathus linearis, which is part of the legume family. That's why it has no caffeine. It's an herbal infusion, or tisane, though most people simply call it tea and that's fine by me.
Can you over-steep rooibos?+
Practically speaking, no. This is one of rooibos's best qualities. Because it has very low tannins, it doesn't turn bitter the way black or green tea can if you leave it too long. You can steep rooibos for 10 or even 15 minutes and it will simply become stronger and richer, not harsh. That said, I wouldn't leave it for an hour. Anything past 10 to 12 minutes starts to taste a little flat rather than full.
Does rooibos taste like black tea?+
Not really. It looks similar in the cup: a warm reddish-amber color. But the flavor is quite different. Black tea has a sharpness, a dryness from tannins, and a certain boldness. Rooibos is softer, naturally sweet, with an earthy and slightly woody quality and hints of vanilla. There's no bitterness at all. People who dislike the astringency of black tea often find rooibos much easier to enjoy.
Can rooibos be drunk cold?+
Yes, and it's wonderful cold. You can cold-brew it by steeping loose leaf or bags in cold water in the fridge for 8 to 12 hours, or brew it hot and strong, let it cool, and pour over ice. The natural sweetness comes forward nicely when chilled. A slice of orange or a few mint leaves turn it into a real summer drink.
Where does rooibos grow and why only there?+
Rooibos grows only in the Cederberg mountain region of South Africa, roughly 200 miles north of Cape Town. The plant requires a very specific combination: acidic, sandy, nutrient-poor soil, a dry mountain climate with cold winters and hot summers, and the particular wild yeasts and microorganisms of that landscape. Every attempt to cultivate it elsewhere has failed. It's one of the most geographically specific plants used for food or drink anywhere in the world.
