Numi Rooibos: the caffeine-free evening default that does not turn bitter
Naturally caffeine-free, low in tannins, and it will not go astringent however long you forget about it. The most useful tisane to keep in the house.

What it is
Rooibos is a shrub from a single region of South Africa's Western Cape. It is not tea, contains no caffeine, and has a chemistry that means it simply does not develop bitterness with long steeping.
In the cup
Sweet vanilla-adjacent woodiness, a little honey, a deep red liquor. Comforting rather than complex.
Brewing
Boiling water, covered, seven to ten minutes. Then leave it another ten if you get distracted — it genuinely does not matter. That property makes it the best tisane for people who make tea and then wander off.
What we will and will not claim
Caffeine-free and low-tannin are established properties and they are why this is the standard evening and child-friendly recommendation. Broader health claims for rooibos rest on thin human evidence and we are not going to make them.
The verdict
Not exciting, extremely useful. The tin you reach for at nine in the evening for the rest of your life.
Best for the evening cup, and anyone cutting caffeine without giving up the ritual.
