Serebrianka (aka Silver) is a Russian aroma hop, and is one of Cascade’s parents along with a Fuggle. Serebrianka was tested for 20 years in the U.S. before being discarded due to low yield, vigor, and storage stability (53%) and susceptibility to disease. It is still available for homebrewing use. It has nice aroma characteristics, and is probably related to the Saazer variety. It has high humulene and farnesene (12%) which contributes to its pleasant aroma and taste.
