Does rooibos tea have caffeine? No — rooibos is naturally caffeine-free. The reason is simple: it isn't a "true" tea at all. Rooibos is a herbal tisane brewed from the leaves of the rooibos, or "red bush," plant — a shrub native to South Africa — not from Camellia sinensis, the tea plant behind green, black, white and oolong teas and the caffeine they carry. That is exactly why rooibos has become such a popular any-time and evening cup.
Does rooibos tea have caffeine? The short answer
No. Pure rooibos contains no caffeine, and it never did — there is simply none in the plant to extract. So is rooibos tea caffeine free? Yes, completely, when it is unblended. This is different from decaffeinated tea or coffee, where caffeine is present and then mostly stripped out; with rooibos you start from zero, which is why it is described as naturally caffeine-free rather than "decaf." The rooibos caffeine content of the plain herb is effectively nil, so any search for "rooibos tea caffeine free" lands in the same place. And if you have seen it sold as "red tea" or "red bush tea," the answer holds: does red tea have caffeine? Not when "red tea" means rooibos.
Naturally caffeine-free is not the same as decaf
It is worth drawing a line between the two. Decaffeinated tea and coffee begin with caffeine that is then removed by a solvent, water or carbon-dioxide process, which almost always leaves a small trace behind. Rooibos skips that step entirely: with no caffeine in the leaf, there is no residue and no processing needed to make it caffeine-free. That is a genuine, built-in zero rather than a reduced number. If you want to see how the removal process works on true tea, our guide to caffeine-free and decaffeinated teas walks through it.
Why rooibos has no caffeine to begin with
Rooibos comes from Aspalathus linearis, a needle-leaved shrub in the legume family that grows almost exclusively in the Cederberg mountains of South Africa's Western Cape. When the fine leaves and stems are harvested, bruised and left to oxidise, they turn the deep red-brown colour that gives the drink its name. Because this bush is botanically unrelated to the tea plant, it produces no caffeine as part of its make-up — so there is nothing to remove, and nothing to leach into your cup. For the full story of the plant, its history and how it is processed, see our guide to what rooibos tea is.
How rooibos differs from true teas
The word "tea," used strictly, means a drink made from Camellia sinensis. Every true tea — green, black, white, oolong, dark and yellow — comes from that one plant, and every one of them contains caffeine. What changes is the amount, which shifts with the leaf, the growing conditions, how long you steep and how hot the water is. Rooibos sits outside that family altogether, alongside other herbal infusions such as chamomile, peppermint and hibiscus.
Here is how rooibos compares with the caffeinated drinks it often replaces. Treat the figures as rough guides only — real values depend on the brand, the leaf, the amount used and how long you brew:
| Drink | Source plant | Caffeine per cup (approx.) |
|---|---|---|
| Rooibos (red or green) | Rooibos bush (Aspalathus linearis) | None — caffeine-free |
| Green tea | Camellia sinensis | Around 25–45 mg |
| Black tea | Camellia sinensis | Around 40–70 mg |
| White tea | Camellia sinensis | Around 15–45 mg |
| Oolong tea | Camellia sinensis | Around 30–50 mg |
| Coffee | Coffee bean (Coffea) | Around 80–100 mg |
| Rooibos chai / blend with real tea | Rooibos plus Camellia sinensis | Some — depends on the blend |
In other words, rooibos is the only row on that list with a firm zero — every drink made from the tea plant, and coffee too, brings some caffeine to the cup.
The exceptions worth checking on the label
Plain rooibos is caffeine-free, but a handful of products built around it are not:
- Rooibos blends with real tea. Some "rooibos chai" or breakfast-style blends mix rooibos with black or green tea for extra body and a lift. Once Camellia sinensis is in the tin, the cup carries some caffeine.
- Bottled and ready-to-drink versions. A canned "red tea" or iced rooibos drink may be blended with black tea or other ingredients, so its caffeine level can differ from loose rooibos.
- Flavoured mixes. Added fruit or botanicals are usually caffeine-free too, but the base is what counts — if it lists green or black tea, it is no longer caffeine-free.
The rule of thumb: pure rooibos is caffeine-free, but anything that combines it with a true tea is not. When in doubt, read the ingredient list. This is the same logic that applies when people ask whether chamomile tea has caffeine — the pure herb has none, but a blend can change that.
Red vs green rooibos: both caffeine-free
You may see "green rooibos" sold alongside the familiar red kind. The difference is only oxidation: green rooibos is left unoxidised, so it keeps a lighter colour and a grassier, more delicate flavour. Both come from the same bush, and both are completely caffeine-free.
Why people choose caffeine-free rooibos
Because there is no caffeine to weigh up, many people reach for rooibos in the evening, later in the afternoon, or any time they want a warm drink without a stimulant. It is a common pick for anyone who is sensitive to caffeine, and in many households it is the naturally caffeine-free cup offered to children. Rooibos is also low in tannins, which is part of why many people find it smooth and mildly sweet rather than bitter, even when it steeps for a long time.
That flexibility is really the point. Where a caffeinated tea has a natural cut-off in your day, rooibos does not — you can enjoy it with breakfast and again close to bedtime without it affecting sleep. Many people also find it sits more comfortably than coffee or strong tea on an empty stomach, though as ever, responses vary.
Any wellness points beyond the caffeine question are a separate story — responses vary from person to person, and none of this is medical advice, so check with your own healthcare provider if you have specific concerns.

Brewing notes: milk, honey and re-steeping
Rooibos is forgiving to brew. Use water just off the boil and steep for around five to seven minutes — because it has no tannins to turn harsh, it will not grow bitter if you leave it longer. It takes milk and a little honey well, which makes it a natural stand-in for a mug of black tea. The leaves also hold up to a second steep, so you can often get more than one cup from the same spoonful.
So, does rooibos tea have caffeine? No — and that single fact explains much of its appeal. A naturally caffeine-free, low-tannin, gently sweet red cup that you can drink at night, share with the whole family, and dress up with milk or honey covers ground that a caffeinated tea simply cannot. Just remember the one caveat: the moment rooibos is blended with a true tea, the caffeine-free promise no longer holds — so let the label be your guide.
