Hop: Cluster


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).

Did you know?
  • Dwarf variety hops grow shorter in height than traditional varieties but, importantly, produce the same yield. This combination makes harvest easier.
Recently added hops
  • Storage: is based on the percentage of alpha acids remaining after 6 months at 20*F.
  • Oil composition percetages are based on the total percentage of oil in the hop. Example: 10 - 20% means that for the specific oil it is 10 - 20% of the overall oil make up.
