Rooibos: The Caffeine-Free Cup That Takes Milk

What rooibos is

Rooibos comes from Aspalathus linearis, a shrub that grows only in the Cederberg region of South Africa. The needle-like leaves are cut, bruised and oxidized, which turns them from green to the deep red-brown you recognize.

It contains no caffeine and very little tannin. That second point is the practical one: tannins are what make over-steeped black tea harsh, and without them rooibos stays smooth no matter how long you forget about it.

Red vs green rooibos

Red rooibos is the oxidized standard — sweet, woody, slightly vanilla-like, with enough body to stand up to milk. Green rooibos is unoxidized, pale gold in the cup, lighter and more herbaceous, closer to a mild green tea in character.

Beginners should start with red. Green rooibos is worth trying once you know whether you like the base flavor at all.

How to brew it

Rooibos is the most forgiving thing in this guide. Boiling water, a heaping teaspoon per cup, and five to seven minutes. Ten minutes will not ruin it. A pot left on the counter for an hour is still drinkable.

Because there is nothing to over-extract, it is also the ideal candidate for a thermos, a slow cooker of spiced tea, or a stovetop latte.

• Leaf: 1 heaping tsp (2–3 g) per 8 oz (240 ml)
• Water: 212°F (100°C), full boil
• Time: 5–7 minutes; longer is fine
• Latte: simmer 2 tsp in 4 oz (120 ml) water for 5 minutes, strain, top with steamed milk

Where it fits in a week of tea

Rooibos solves the six-o'clock problem: you want another mug, but not more caffeine, and chamomile feels too slight. It takes milk and sugar like a breakfast tea, so the habit transfers directly.

It is also the base for a good caffeine-free chai — simmer it with cinnamon, cardamom, ginger and cloves, then add milk. Nutritionally it is rich in antioxidants, though the specific health claims made for it are less well supported than the marketing suggests.
