Green Tea

Unoxidized tea with a fresh, vegetal character.

Overview

Green tea is produced from the same plant as black tea but is not oxidized. It retains higher levels of catechins and has a lighter colour and flavour.

Production method

Leaves are quickly heated (steamed or pan-fired) to prevent oxidation, then rolled and dried.
