Stability in storage:



Here is some guidance for your homebrewing hop additions:

  • For bittering, add hops as desired no later then 15 minutes from end of the boil.
  • For aroma, add hops 5-15 minutes from end of the boil.
  • For flavor, add hops 2-5 minutes from the end of the boil.
  • For dry-hop character, add directly to the primary or secondary fermenter.
  • The specific hop amount needed for a 5 gallon (18.9 liter) batch will vary. The main factors that determine the quantity of hops that you need are the alpha acid content of your hops, the boiling time that you select, and the bitterness targets for your recipe.

    Use our Hop Utilization, Hop Bill, and Hop Alpha Acid Loss Calculators to help you do the math to help determine how to best use Pacific Gem hops in your next homebrew recipe.


    In general, you prepare your hops for use in beermaking by:

  • Ensuring that they are stored in sealed containers under refrigeration for maximum freshness prior to use.
  • Pre-measuring the amounts you plan to add for different stages of the wort boil.
  • Note that hops are available to brewers in a variety of forms (whole, plug, pellet).
