Oolong Oxidation Quiz – From Green to Dark Roasted Teas

All true tea comes from the same plant, Camellia sinensis, and oxidation shapes much of the difference. Green tea is heated soon after picking, black tea is fully oxidized, and oolong sits in between.

Oolong makers wither the leaves, then toss or bruise them so enzymes react with oxygen at the edges. When the tea reaches the right level, a kill-green step with heat stops oxidation, and the leaves are rolled and dried.

Lightly oxidized teas such as Tieguanyin and Taiwan's high mountain oolongs taste floral, while roasted Wuyi teas like Da Hong Pao taste toasty. Gongfu brewing uses many short infusions to taste every change.
