A powdered black tea drink mix is prepared by subjecting to extraction with hot water at a temperature of between about 60°and 130°C., separating the tea leaves from the extract; concentrating this first extract to a solids content of between about 5 and 12% and cooling the first extract to a temperature of between 5°and 15°C. in order to form an insoluble tea cream which is separated from the first concentrated extract. This tea cream is mixed with the spent black tea leaves or with green tea leaves to form a mixture which is extracted with water at a temperature greater than about 70°C. in order to obtain a second extract which is separated from the spent leaves. The first and the second extracts are mixed, concentrated to the desired solids content and dried to form the powdered drink mix.

A process for the preparation of a black tea powder product which comprises: treating black tea leaves with water at a temperature of between about 60°and 130°C. for a sufficient time to form a first extract and spent black tea leaves; concentrating the first extract to increase the solids content; cooling the concentrated first extract to precipitate an insoluble tea cream containing residue; separating said insoluble tea cream containing residue from said cooled and concentrated first extract to yield a separated first extract; mixing the separated residue with one of the spent black tea leaves or green tea leaves to form a first mixture, wherein the quantity of green tea leaves, if used, is less than the quantity of black tea leaves used to form the first extract; treating the first mixture with water at a temperature greater than 70°C. up to about 100°C. for a sufficient time to obtain a second extract; separating said second extract from said treated mixture to yield a separated second extract; mixing portions of the separated first extract and separated second extract to form an extract mixture; and drying the extract mixture to form the black tea powder product.
