|Alpha Acid % (AA)|
Alpha acids are the main source of bitterness in beer. Longer boil times will result in isomerization of more alpha acids leading to increased bitterness. Learn more »

Opal Hop Substitutions
If the Opal hop is hard to find or if you are simply out of it on brew day, you can try to substitute it with a similar hop.

Is Opal available in lupulin powder?
Unfortunately, there is no lupulin powder version of the Opal hop. Neither Yakima Chief Hops (Cryo/LupuLN2), Haas (Lupomax) or Hopsteiner have created versions of this hop variety in lupulin powder form yet. Too bad too - it is pure hop lupulin powder, which leads to huge, concentrated flavor when used in the whirlpool or dry hop additions.
