Rooibos Tea: What It Is, Taste, Caffeine and How to Brew It
What is rooibos tea? Rooibos (say “roy-boss”) is a herbal tea made from the leaves of Aspalathus linearis, a shrub that grows only in the Cederberg region of South Africa’s Western Cape. The name means “red bush” in Afrikaans. It brews a reddish-amber cup with a mild, naturally sweet, slightly nutty taste, it is naturally caffeine-free, and it is low in tannins, so it does not turn bitter.
If you love the ritual of a cup of tea but want something you can drink late in the evening, rooibos is one of the easiest switches. It looks and drinks like a light black tea, works with or without milk, and makes an excellent iced tea. Here is what it is, how it tastes, what the research says and how to brew it.

Where rooibos comes from
Rooibos is a shrub native to a small mountainous area around the Cederberg in South Africa’s Western Cape, and it is still grown mainly there.1 The needle-like leaves are cut, bruised and left to oxidise, which turns them red and develops their sweet, woody flavour. A less common “green rooibos” is not oxidised and tastes more malty and grassy.1
What does rooibos taste like?
Red rooibos is smooth, mildly sweet and slightly nutty, with woody, honey-like notes and almost no bitterness. Because it is low in tannins, you can leave the tea bag in longer without the cup turning harsh.1 It pairs well with milk, lemon, vanilla, cinnamon or a little honey.
Does rooibos tea have caffeine?
No. Rooibos is not from the Camellia sinensis tea plant, so it is naturally caffeine-free.1 That makes it a good evening cup and a gentle option for anyone avoiding caffeine. See how it compares in our caffeine chart.
Rooibos tea benefits: what we know
- Caffeine-free and low in tannins. These are its most practical benefits: you can drink it at night, and it is gentle and never bitter.
- Naturally rich in plant compounds. Rooibos contains polyphenols such as aspalathin, which is found almost only in this plant. Much of the research on them has been done in the laboratory and in animals, and good human studies are still limited, so health claims should be treated with caution.
- An easy swap for sugary drinks. Because rooibos tastes naturally sweet, many people find they need little or no sugar.
