Rooibos is a South African shrub, not a tea plant. No caffeine. Naturally sweet, slightly earthy, with a warm red color. It steeps like a black tea: boiling water, five minutes. It does not go bitter no matter how long you leave it. We carry it straight and in blended versions: rooibos chai, rooibos vanilla chai. A good option for anyone replacing black tea without wanting to lose the richness.
