Rooibos (pronounced ROY boss) is South African red bush, a small leafed shrub native to the Cederberg mountains of the Western Cape. It's not technically tea. The plant is Aspalathus linearis, no relation to Camellia sinensis. But it's brewed and consumed exactly like tea, and it has built a strong following on the British shelf as the natural, completely caffeine free alternative for evenings, pregnancy, and anyone trying to cut caffeine without giving up the cup of tea habit. You'll see rooibos sold under several names, often interchangeably: Rooibos , the South African name, the technically correct one Redbush , the English translation, used by Tetley and most UK supermarket brands Red tea , informal name in some markets, can be confused with Chinese black tea
 They are the same thing. The names are a marketing choice, not a difference in the leaf. See the dedicated redbush range for the British shelf naming and the rooibos range for the wider category. Where rooibos comes from

Canonical: https://teas.co.uk/wiki/rooibos-tea/ Rooibos grows only in the Cederberg region of South Africa, a roughly 100km stretch of mountainous terrain north of Cape Town. The plant has never successfully been cultivated commercially anywhere else, partly because it needs the specific Mediterranean meets arid climate of that area, and partly because the wild plant has a deep taproot that resists transplanting. The harvest is a manual process. Workers cut the bush to about 50cm above ground, the cuttings are bruised, oxidised in the sun (which gives red rooibos its characteristic red colour), then dried. Green rooibos is the same plant but the oxidation step is skipped, leaving the leaf its natural pale green and giving a lighter, grassier cup. Red rooibos vs green rooibos

 Red is what almost everyone in the UK means when they say "rooibos". Green rooibos is a niche product, mostly sold by specialist tea retailers. How to brew rooibos 

Source: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for How to brew rooibos, Rooibos Tea. Canonical: https://teas.co.uk/wiki/rooibos-tea/ Rooibos is the most forgiving brew on the shelf. It does not get bitter no matter how long you leave it, and it tolerates boiling water without any of the bitterness problems green tea has. Temperature: 95 to 100°C, freshly drawn. Boiling is fine. See the water temperatures guide for the full breakdown. Steep: 5 to 7 minutes for full character. Longer is fine, the cup keeps developing without going harsh. Leaf: One bag per mug, or 1g of loose leaf per 50ml of water. Milk: Optional. Red rooibos takes a splash of milk well, especially the vanilla and chai variants. Green rooibos is better drunk black. Re infusions: Most rooibos teabags exhaust on the first cup, but loose leaf rooibos can be re infused once.
 The "leave it as long as you like" character is what makes rooibos a kitchen workhorse. Forget you made the cup, come back 20 minutes later, the tea is still drinkable. Try that with a green tea and you'll regret it. Caffeine and other chemistry

Canonical: https://teas.co.uk/wiki/rooibos-tea/ Rooibos is naturally caffeine free. Not "decaffeinated", not "low caffeine", but truly caffeine free because the plant has never contained caffeine in the first place. This is the single most important reason rooibos has built an audience in the UK. The use cases that drive most rooibos purchases: Evening cup , no risk of disrupting sleep Pregnancy , the NHS recommends limiting caffeine to 200mg per day during pregnancy; rooibos lets you keep the cup of tea ritual without counting People cutting caffeine , rooibos is the closest non tea alternative to a cup of black tea, far closer than herbal infusions like chamomile or peppermint Children , rooibos is widely given to children in South Africa from infancy; the lack of caffeine and tannins means no iron absorption interference
 Rooibos is also low in tannins compared to true tea, which means it doesn't have the iron absorption interference that black or green tea does. For people with iron deficiency anaemia, rooibos is the safer option to drink alongside meals. For more on the caffeine context across all tea families, see the ultimate caffeine guide. A note on health

Canonical: https://teas.co.uk/wiki/rooibos-tea/ Rooibos contains two unusual antioxidants, aspalathin and nothofagin, which have been studied for various effects. The honest reading is modest: any benefits are small, and nothing here is a reason to treat the cup as medicine. The supplement industry sells rooibos extracts at high doses with claims about everything from skin health to cancer prevention. For a cup of tea drinker the reality is simpler: rooibos is a low-calorie, naturally caffeine-free, polyphenol-rich drink that tastes good. That is the case for drinking it; treat the bigger health claims with the same scepticism you would apply to any superfood marketing. Rooibos blends, the British shelf

Canonical: https://teas.co.uk/wiki/rooibos-tea/ Plain red rooibos is the workhorse. It also blends extraordinarily well with sweet, warming and spice flavours because the natural sweetness in the leaf carries them. The most common blends on the UK shelf: Vanilla rooibos , the classic dessert leaning version, the warming pairing of vanilla and the natural rooibos sweetness Rooibos chai , the caffeine free alternative to traditional masala chai, same spice canon (cinnamon, cardamom, ginger, clove, black pepper) but on rooibos rather than black tea Earl Grey rooibos , bergamot oil on rooibos, the caffeine free version of Earl Grey Rooibos with citrus or fruit , lemon, orange, berry blends Honeybush blends , pairing rooibos with the related but sweeter honeybush plant from the same region

Canonical: https://teas.co.uk/wiki/rooibos-tea/ Rooibos is genuinely different from Camellia sinensis tea.

 The closest cup experience to rooibos is actually a lightly brewed black tea with a splash of milk and a pinch of cinnamon. Once you've drunk both side by side, the differences are obvious, but rooibos is the family that's most likely to satisfy a black tea drinker who needs to cut caffeine.

Why rooibos suits sensitive drinkers

Source: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for Why rooibos suits sensitive drinkers, Rooibos Tea. Canonical: https://teas.co.uk/wiki/rooibos-tea/One plain, practical reason rooibos appears so often in gentle, soothing recommendations is structural rather than medicinal: it is naturally caffeine free and naturally low in the tannins that make strong true tea astringent, which makes it easy on people who find black or green tea harsh, acidic or over stimulating. It is a South African plant (Aspalathus linearis), not Camellia sinensis, so it is technically a tisane rather than a tea, see what counts as tea. It takes milk or lemon, brews without a bitterness penalty even if over steeped, and is widely used as an everyday or evening alternative when caffeine is unwanted. None of that makes it a remedy; it simply makes it a comfortable, low irritation cup, which is exactly the modest, plain claim worth making rather than the wellness over claims often attached to it.
