Hallertauer Gold

A varietal of the German Institute for Hop Research in Huell, Germany, Hallertauer Gold is a descendant of Hallertau Mittelfrüher and is often marketed under various, similar names. Developed in the mid-1970s, it was released to the public in the late 1980s. A lot of commercially sold Hallertau is usually Hallertauer Gold or Hallertauer Gold combined with Hallertau Mittelfrüher. Its aroma is continental but with higher alpha acids and low cohumulone. This hop was bred to be more wilt resistant than its parent after persistent wilt became an issue in Germany.
