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 oxidise 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 flavour and colour.

A cold water infusible tea leaf product is shown which brews in cold water to produce an iced tea beverage with the color and flavor of iced teas prepared by hot brewing methods. The product when brewed in water at about 15.degree. C. for about 5 minutes at a water to tea ratio of 100 water to 1 tea has a cold water infusion Hunter L Value of about 25 to 45; a Hunter "a" value of about 24 to 34; a Hunter haze value of less than 40 and at least 0.15% soluble tea solids.
Included is a method of processing green tea leaves to produce black tea particles which can be brewed in Cold Water. The method also is designed to produce cold water brewing tea of a suitable size and grade for use within a tea bag. The method also is designed to produce high polyphenol cold brew tea or conventional tea of any suitable size and grade. Thus, by way of the method of the present invention, a black tea is produced that can be brewed in cold water and further which can be used in tea bags. This is achieved without sacrificing any color quality or taste.
