My South African friend put me on to this stuff a few months back and I really like it. Me and caffeine don't get along so well so I usually stick to herbal teas (with the odd green tea/English tea when I'm feelin' a bit crazy) but this stuff seems great hot or cold. Looks like wood chips but tastes damn fine any time of the year. Any other fans? Brands to look out for? Brewing tips? Nutritional fun facts?
