Rooibos tea comes from the dried leaves of the rooibos plant, also known by the scientific name of Aspalathus Linearis It does not come from the tea plant. Although it is difficult to describe the flavor accurately, rooibos has a fruity, nutty, floral, and slightly sweet taste.
To make rooibos tea, the leaves of the plant undergo an oxidation (fermentation) process. During this fermentation process, an enzymatic process occurs which causes the leaves to turn the rusty red color that rooibos is famous for. The leaves are left to dry in open fields under the sun.
