Hops don’t like to get old either
Hop aging | When hops age, chemical changes occur that reduce their brewing value. As long as the hop cone is on the hop bine growing in the field, no oxidation happens. As soon as the hop plant is harvested, the clock starts ticking before hops are packaged. The enemies of hops are high storage temperatures and time, as well as whether they are stored in oxidative or non-oxidative conditions. In this first part of an article series we discuss what this means for the brewer, introduce the Hop Storage Index and talk about the economic implications of hop aging.
