The cup is light and gently herbaceous, with the slightly green character distinctive to guava leaf. The 60g pack contains tea bags ready to brew. Brew in freshly boiled water for 4 to 5 minutes. Caffeine-free. Sipacupa is a UK Jamaican tea brand specialising in traditional single-herb bush teas — guava leaf is one of the more interesting options in their range, particularly favoured by drinkers who already know Caribbean bush-tea traditions.
