The breeding program that resulted in Crystal was fostered by Dr. Alfred Haunold in 1983 at Oregon State University in Corvallis, due to a need to develop hop varieties similar to German noble varieties that would flourish in the Pacific Northwest. American hop farmers had little success cultivating continental hops and importing them was quite expensive for American brewers.
Crystal was the result of a cross between a tetraploid Hallertauer mittelfrueh and a male hop designated USDA 21381M, who’s pedigree included Cascade, Brewer’s Gold, and Early Green. Crystal is half-sister to Liberty, Ultra, and Mt Hood.
Crystal continues to do well within the ever expanding arena of aroma hops. It’s acreage has continually grown over the last five years, and it had the third highest production in metric tons of aroma hops grown in Oregon in 2016.
