BULLION Alpha acid 6-9% Ref: HOPBULL0609 BREWING QUALITY Lends an intense black currant aroma, along with a spicy and pungent bitterness. A good bittering hop for Stouts and Dark ales. ORIGIN / HISTORY UK origin. One of the first varieties developed from a breeding programme circa 1917 by Professor Salmon in England. Bullion has very poor storage characteristics of its soft resins, so its use declined rapidly in the 1980's. Today only a few breweries use Bullion.
