What it is

Rooibos is a South African plant, Aspalathus linearis, whose needle-like leaves are fermented and dried to make a tisane unrelated to Camellia sinensis, the tea plant.

What it tastes like

On the nose: citrus; the house adds honeyed, woody, gentle tea ✳. Among its measured molecules: methylheptadienone, (Z)-2-Heptenal, 1-octen-3-one, (E,Z)-2,6-nonadienal, trans-2-decenal.
