Substitute for Cluster: hops like Cluster

Cluster (United States)

If you cannot get Cluster, this is the closest hop and what changes in the beer.

Close, with a caveat. Northern Brewer or a clean bittering hop is the nearest substitute for Cluster, but the aroma shifts.

Notes

If Cluster is out, another traditional American dual-purpose hop covers the bittering; the light blackberry aroma is harder to match.

For a clean bittering charge any high-alpha hop works; to keep Cluster's spicy-blackberry note, a traditional variety is closer than a modern citrus hop.
