Origin and Description
Liberty Hops is an extension of the Hallertau family of hops and was bred in 1983 from Hallertauer Mittlefrüh and a disease (Downy Mildew, Verticillium Wilt) resistant male, otherwise known as USDA 64035M. Liberty Hops has some notable relatives, as it is half sister to Ultra, Mt. Hood Hops, and Crystal Hops.
Like its German heritage, from the largest growing hops region in the world (Hallertau), Liberty Hops is an aroma variety with an alpha acid rating of 3.0%-6.0%. This variety, which was released in 1991 is likened to noble hops varieties, and comes with a delicate floral bouquet that has essence of spice. Liberty Hops is used in many different fashions and in many styles of beers. It will contribute bitterness at the beginning of a boil, and is used in that capacity often. Liberty is more aggressive on the aroma contribution late in the boil, as it comes equipped with high levels of humulene and caryophyllene oil. Humulene provides the earthy spice and withstands heat better than caryophyllene, which is known for its essence of grapes, peaches, and vanilla.
Liberty Hops is in wide use in many beers, mostly in the U.S. but also world wide. Its important that fresh hops are used, in the case of liberty, as its storage capacity is near the bottom. The yield for Liberty is very low, and the medium compact cones come early to mid season after a vigorous growth cycle. Success was attained at creating a mildew resistant strain, as Liberty has a high tolerance for Downy Mildew.
