Rooibos, or 'red bush' tea, is a naturally caffeine-free tea that grows only in south africa's cedarberg mountains. While traditional black and green teas are made from the leaves of the camellia sinensis, rooibos is made from aspalathus linearis, a shrub unique to this protected world heritage site. In general, red rooibos has a sweet, honey aroma with malty, tobacco flavors and dried cherries, vanilla notes. It has a low level of tannin, so doesn't have the bitter taste that you can find in teas made from camelia sinensis tea plants. The big difference to black tea is that redbush is low in tannins and therefore is sweeter and won't go bitter no matter how long you leave the teabag.
