Saaz hops
Saaz is a "noble" variety of hops. It was named after the Czech city of Žatec (German: Saaz). This hop is used extensively in Bohemia to flavor beer styles such as the Czech pilsener. Saaz hops accounted for more than 2/3 of total 2009 hop production in the Czech Republic.[1] It is the main hops variety used in the production of global beer Stella Artois.
Characteristics
Saaz has a very distinctive flavour. When used in beer, the resultant aroma is very mild, earthy, herbal and spicy. Despite its popularity and noble pedigree, Saaz generally has a very low Alpha Acid level and is not very effective as a bittering hop. This hop is generally used for Bohemian style lagers and pilseners.[2]
Another variety of Saaz hops has been propagated in the United States of America. The US variety has a higher Alpha Acid content than the original Czech variety.[3]
