We are not even sure that Africa has an autumn, but the marriage of herbal rooibos (red bush), cranberry and oranges suggests that in our imaginations, it does! The base of Harney & Sons African Autumn, our popular herbal blend, is rooibos – a legume also known as 'red bush' native to South Africa. Rooibos is oxidized, which changes the color to red, and when brewed, it looks similar to the red of "black" tea. Loaded with antioxidants, fans love the brightness of the rooibos accented by cranberry and citrus. Caffeine free.
