Hop tannins. Flavonols in some Czechoslovak and foreign hop varieties (part 2.).Peer-reviewed article

J. HUBÁČEK, M. TROJNA

The article presents the results of research works investigating the proportions of kempherol and quercetine in some varieties of the Czechoslovak and foreign hops. The Žatec sorts of hops are outstanding for their well balanced relation between the two components. This balance is one of their specific features distinguishing them from British and American varieties. The proportions of individual flavonole aglycones can be used as criteria for classifying hops into several quality groups, since the properties of hops depend largely on the relation between the mentioned components.
