Hop Evaluation and Selection

By John Harris Full Sail Brewing Company, Portland, Oregon, USA. This poster was originally presented at the MBAA 112th Anniversary Convention, Keystone, Colorado, 1999.

Abstract
This poster illustrates some of the methods used for hand evalua- tion of hop samples and how to identify common flaws in hops. Brewers have to react to ever-changing raw materials, thus hop selec- tion gives them more control over the flavors of their beers. When evaluating hop samples for purchase, it is important to understand how to properly evaluate the samples. When rubbing hops, many of one's senses have to be employed to assess the hops appearance and aroma. The best way to examine hops is in leaf form, soon after har- vest, because that is when oxidation is at its lowest levels. Proper evaluation techniques will be outlined and photos will be presented to show many of the common flaws found in hop samples and how to identify them. Pellet evaluation will also be discussed.
Keywords: Hop Selection, Hop Evaluation Team, Hop Inspection.
