Rooibos, Aspalathus linearis, the famous caffeine-free speciality from  South Africa, is a beverage which is naturally rich in anti-oxydants, minerals and vitamins. It contains a limited amount of tannin, a substance responsible for the astringent taste of the tea, which is not appreciated by everybody. Rooibos, often called “red tea” is very digest and can be consumed hot or cold at any hour of the day by adults and children.
