Born in 1983, Liberty is half-sister to Crystal, Ultra and Mt. Hood. It originates from Hallertau Mittelfrüher and a disease resistant German aroma male. Liberty’s yield is low but it still enjoys popularity, especially in the US. It is a genetically sterile variety and not suitable for breeding.
Harvest Moon Brewery uses Liberty liberally in their Full Moon Pale Ale along with Cascade. Given its heritage, it’s no wonder Liberty is likened characteristically to noble hops. Brewers should be advised that, due to Liberty’s very poor storage stability, they should be obtained and used fresh where possible.
