Hops - Variety Descriptions

Hops are the female flower cones, also known as strobiles, of the hop plant (Humulus lupulus). They are used primarily as a flavoring and stability agent in beer, though hops are also used for various purposes in other beverages and herbal medicine. The first documented use in beer is from the eleventh century. Hops are used extensively in brewing today for their many purported benefits, including balancing the sweetness of the malt with bitterness, contributing a variety of desirable flavors and aromas, and having an antibiotic effect that favors the activity of brewer's yeast over less desirable microorganisms.
Bittering Hops
Bittering hops usually have a high alpha acid. The bitterness qualities that hops add are from the alpha acids in the lupulins. When boiled, a reaction occurs that creates bitterness and adds a natural preservative to the beer. First noted when India Pale Ale was sent from England to their troupes in India.
Aroma Hops
Aroma hops are noted for their lower alpha acid contents and their fragrance. When added towards the end of the boiling process, these hops produce different levels of hoppy, piney, woody and fruity aromas.
