Hop: Crystal

Description

Crystal was bred at Oregon State University in Corvallis, Oregon by Dr. Alfred Haunoid in 1983. A cross between a tetraploid Hallertau and male USDA 21381M, with pedigree of Cascade, Brewer's Gold and Early Green.

Four other hops came out of the breeding program, making Crystal a half-sister of Liberty, Ultra and Mount Hood.

The focus of the breeding program was to make German noble substitutes that were expensive to bring over and earlier farming had little success. Crystal is an American replacement of Hallertau.

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.
