Cluster is considered to be the oldest hop grown in the United States. It was brought over with European settlers and has been through many years of development, producing offshoots: California Cluster and Yakima Cluster to name a couple.
Cluster is still grown but not in the amounts it once was. Higher alpha hops and/or more disease resistant varietals have taken over.
California Cluster is another version of this hop but is considered to be indistinguishable from Cluster (there may even be other varieties as well). Therefore California Cluster will not be listed separately.
