Spring Citron (TGBOP) - 2014 Produced in April, this olive green speciality is made from the tender two leaves and a bud harvested in the early hours of daybreak in a high section of the plantation. The harvested leaf is roasted at 65.5°C after which the leaf is delicately twisted and roasted once again at 98.5°C. Thereafter, the tea is stored in airtight containers for its natural flavours to emanate, for that added spring sensation.
