Žatecký chmel are hops grown in the districts of Louny, Rakovnik, Chomutov, Kladno, Plzeň-sever and Rokycany in the Czech Republic, locally known as the Žatec hop-growing area. The hops come in the shape of golden yellow cones. They have a typical hoppy scent and a red-coloured bine.
What makes these hops unique is the fact that they have a low alpha-bitter acid content and large amounts of beta-farnesene, not found in other hops. The growing of hops has a thousand-year-long tradition in the Czech Republic and its origin was labeled and verified since the 16th century.
