Grow your own hops with a rhizome root stock.
Liberty is an American aroma hop with an alpha acid percentage ranging from 3-5%. Designed as a substitute for Hallertau Mittelfruh, Liberty makes an excellent domestic stand-in for European noble hops in German pils, Bavarian-style lagers, Kolsch, Hefeweizen, Biere de Garde, and Belgian ales. Mild and refined, Liberty's aroma is spicy, sweet, grassy and haylike.
Cascade, Magnum, and Nugget hops are the recomendated hops for beginner growers.
