Hop: Keyworth's Early


Keyworth's Early is an old English aroma hop that has been limited due to low yield but had high acreage early on due to Verticillium wilt resistance.

The hop was released in 1949 from East Mailing Research Station in Kent, Keyworth. Descended from a New Mexican wild hop and open fertilization.

After almost disappearing, it has seen a revival with Charles Faram's with descriptors of lemon and grapefruit aroma.
