Bullion lends an intense black currant aroma, along with a spicy and pungent bitterness. It is a good bittering hop for stouts and dark ales. 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. It is susceptible to downy mildew but no adverse virus responses. It is available in leaf and T90 hop pellets.
