Hop: Bullion

Hops Catalog

Description

Bullion breeding started in 1917 with the goal of combining European aroma with American high resin by Professor Ernest Salmon. A wild hop from Manitoba, Canada was the mother, being open pollinated in 1918. Brewers Gold and Bullion were selected from this process.

Bullion was eventually released in 1938. Once released mainly grown in United States in Canada, never really taking off in the United Kingdom.

Bullion was a major hop variety in the mid-1940s, later discontinued from United States production in 1985.

Did you know?
  • Dwarf variety hops grow shorter in height than traditional varieties but, importantly, produce the same yield. This combination makes harvest easier.
Explanations
  • Storage: is based on the percentage of alpha acids remaining after 6 months at 20*F.
  • Oil composition percetages are based on the total percentage of oil in the hop. Example: 10 - 20% means that for the specific oil it is 10 - 20% of the overall oil make up.
