Green Tea, Oolong Tea, and Black Tea are produced from the leaves of Camellia Sinensis, which contains caffeine naturally.
Oxidation decreases Catechins and EGCG in tea leaf. There are two ways to stop oxidation after tea leaf is harvested: Steam or Panning. Both methods kill the enqyme causing oxidation in tea leaf. Scientific tests show tea steaming method offers higher Catechin & EGCG amount than panning method.
Typically, Japanese green tea uses steaming method, and Chinese green tea uses panning method.
