- (c) adding the herb tea infusion to black tea leaves at ambient temperature for a period of time sufficient to achieve good contact of the tea leaves with the water to form an aqueous tea extract/tea leaf mixture;
- (d) heating the mixture to a temperature of at least 60.degree. C.;
- (e) separating the aqueous tea extract from the extracted black tea leaves;
- and then
