Liberty is an American aroma hop variety developed by the USDA in 1983 and released in 1991. Bred from Hallertau Mittelfrüh and a downy mildew-resistant German male, Liberty closely resembles its noble parentage, offering mild, sweet, and floral characteristics with subtle spicy notes. It is well-suited for German-style lagers and ales, as well as American craft lagers.
Liberty was developed to provide an American alternative to the traditional German Hallertau Mittelfrüh, aiming to replicate its noble aroma profile while offering improved disease resistance.
