Provided herein is a method of improving the taste profile of a glucosylated terpene glycoside (GTG) comprising: a) mixing a malted cereal with a glucosylated terpene glycosides in water to form a GTG cereal mixture wherein the cereal comprises an amylase; b) adjusting the temperature of the mixture to a temperature sufficient to activate the amylase and for a time sufficient to form a mixture comprising glycosylated steviol glycosides wherein the average number of glucose units of the GTG in the GTG cereal mixture is reduced.
