California Cluster

Generally considered to be indistinguishable from other Cluster varieties, California Cluster is a true dual use hop. Used prolifically by US brewers in the early-to-mid 1900’s, Clusters were widely available and cheap – providing a generic but pleasant bitterness and flavor.


California Cluster’s exact lineage is vague. The name itself is also representative of a number of different Cluster varieties. The original California Cluster though is widely noted to be the parent of Calicross and was successfully employed over 50 years ago to produce disease resistant strains, Smooth Cone, Calicross and First Choice.

Hops-Meister hop farm in Clearlake, California claim to have reintroduced two of the “original” variations of California Cluster, trademarked Ivanhoe and Gargoyle. It is unclear exactly which cluster varieties they are however.
