Abstract
A method for preparing a cold water infusing leaf tea. Green tea leaves are macerated, treated with tannase, fermented in the presence of hydrogen peroxide in an amount that is sufficient to activate endogenous peroxidases to oxidize gallic acid and other compounds that are liberated by the tannase treatment, and then dried. The final product is a black leaf tea that infuses in hot or cold water to give good flavor and color.
