Keyworth's Early Hops

Dual: Aroma and BitteringAlpha 6.5 - 8.5%United Kingdom

Keyworth's Early is a rugged pioneer of the mid-century British hop industry and a direct relative of the Midseason variety. Released in 1949 from the East Malling Research Station in Kent, it was developed by Professor Salmon as a vital defense against Verticillium wilt. By blending the untamed genetics of a wild New Mexican hop with traditional British stock, Salmon created a variety with a "New World" intensity decades before the concept existed. Although its commercial acreage eventually declined due to lower yields compared to its siblings, it has seen a modern revival through Charles Faram, remaining a landmark variety for brewers exploring the high-oil, high-impact roots of historical English ales.

The profile of Keyworth's Early is a pungent and soulful arrangement of bright citrus and dark forest fruits. It leads with a primary bouquet of lemon zest, grapefruit, and wild blackberry, followed by a sophisticated secondary layer of sticky pine resin and earthy tobacco. Unlike the polite, floral hops common in the 1940s, Keyworth's Early is assertive and bold, offering a "wild" aromatic edge and a peppery spice that cuts through heavy malt bills. On the palate, it imparts a firm and lasting bitterness that provides the perfect counterpoint to the rich, biscuit-like sweetness of Maris Otter malts, making it the definitive choice for recreating authentic, historical strong ales.

Substitution Tip

If you can't find Keyworth's Early, the best alternatives are Bramling Cross, Brewer's Gold, Bullion, or Northern Brewer.
