Caffeine free Rooibos tea is made from the leaves of the Aspalathus Linearis (or "red bush") plant, which grows only in the small Cederberg region of South Africa. Because it does not derive from the Camillia sinensis plant (like black, white, green or oolong teas), rooibos tea is considered more of an herbal drink or tisane than a "true" tea. Rooibos tea is often called "red tea" or "red bush" tea because of the bright red coloring the leaves take on during the oxidation and fermentation processes. A properly brewed cup of Rooibos tea will be a rich red color and have a sweet, nutty flavor and is traditionally served with milk and sugar in its native South Africa. Use 1.5 tsp of Rooibos tea for every 8 oz cup of boiling water and steep about 5-6 minutes. For equally delicious Rooibos iced tea, just double the amount of tea used, steep at the same temperature and for the same length of time, then pour the tea directly into a glass full of ice.
