Hop measurement


There are two ways to measure hops for use in brewing. The first way measures the bittering potential of the hops going into the boil.
Alpha Acid Units(AAUS) or homebrew bittering units(HBUS), are the weight of hops multiplied by the percentage of Alpha acids.
This unit is convenient for describing hop additions in a recipe because it indicates the total bittering potential describing hop additions
in a recipe because it indicates the total bittering potential from a particular hop variety while allowing for year to year variation in the % AA s.
 
Firstly, Here I will introduce how to Calculate Alpha Acid Units
AAUS are a good way to state hop additions in your recipes. By specifying the amount of alpha acid for wach addition,
rather than e.g. 2 oz of cascade, you do not have to worry about year to year variation in the hop. An AAU is equal to the % AA multiplied by the weight in ounces.
 
For example: 1.5oz of cascade at 5% alpha acid is 7.5 AAUs. If next year the alpha acid percentage in cascade is 7.5%,
you would only need 1 oz rather than 1.5 oz to arrive at the same bitterness contribution.
AAUS= weight (oz) * % Alpha Acid
