Abstract
The isolation of at least one water soluble glycoside comprising an aromatic moiety group conjugated to mono-, di-, and trisaccharides from hop plant parts other than hop cones is disclosed. A glycoside preparation made by extraction of hop plant leaves with an aqueous alcohol was discovered to confer a pleasant grape flavor to the beer to which the glycoside preparation was added. The glycoside composition of the glycoside preparation made from aqueous alcohol-extracted hop plant leaves was found to differ from a similar preparation made from hop cones.
