Hops Lose Alpha Acids In Storage (Part 2 of 3)

Scan 1

Alpha acid loss in two hop varieties over time, estimated from data from Hop Union. (In reality, the rate of loss is likely not linear. See the next article for more details.)

As I detailed in the first half of this article, hop alpha acids levels decline during storage. Proper handling can slow the degradation of the alpha acids, but even properly stored hops gradually lose their bitterness over time. In this post, we’ll examine if the loss if alpha acids is great enough to matter, and how to account for it if you do wish to take it into consideration. [Read more…]
