BarthHaas

Cluster

United States

DESCRIPTION

Cluster is the oldest variety grown in the U.S. Until the late 1970's, Cluster was one of only a few varieties growing in the U.S. and was planted to most of the hop acreage. The choice of name may be connected with the way in which the fruits are arranged in clusters. The origin of the rootstock, however, is unknown.

ANCESTRY

Unknown-- but possibly a cross between English variety and US male hop
