Rooibos and honeybush both originate in the Cape region of South Africa. They both produce caffeine-free infusions without any bitterness, which are ideal either hot or iced. As for tea, depending on the degree of oxidisation, a "green" or "red" version is obtained. The green version gives a more fluid drink, while the red transfers more of its substance into the liquor. The increasing popularity of these products following a number of studies into their effects has unfortunately led to prices rising over the last two years – but the pleasure they bring is well worth the still relatively modest price.
