Hops are the female flower cones of the hop plant (Humulus lupulus) They are used primarily as a flavoring and stability agent in beer, beer, other beverages and in herbal medicine medicine.. Hops contain several characteristics favorable to beer: balancing the sweetness of the malt with bitterness, contributing flowery, citrus, fruity or herbal aromas, aromas, and having an antibiotic effect that favors the activity of brewer's yeast over less desirable microorganisms microorganisms.. The first documented use in beer is from the eleventh century.. century The hop plant is a vigorous climbing herbaceous perennial (20(20-30 years). Can be easily grown organically Alpha & Beta Acids Contained in Lupulins Lupulins Alpha acids add bitterness to beer - take approx. 1 hr of boiling to release - high and ultra high alpha acid hops used for bittering (can use most hops to bitter) Low alpha acid hops used for flavoring and aroma Photo by HopUnion Photo by Dr. Ron Godin Photo by HopUnion -Take approx. 2-5 minutes or can be dry hopped 1
