Crystal hops are an American bred and grown variety that is the daughter of Hallertauer Mittelfrüh. Crystal also has genetics from Cascade and Brewer's Gold, but is used mostly for its noble German character. Crystal offers a light aroma of floral and cedar with some soothing spices in the background. Crystal was first released in 1993 by the USDA and is the half-sister of Mt. Hood and Liberty.
