	Hop bitterness is measured in [[International Bitterness Units]] or ''IBU's''. One IBU is one part per million of ''isohumulone'' which is a bittering (alpha) acid. IBU's can be estimated when brewing a beer by several different formulas, the most popular of which are the ''Tinseth'', ''Rager'' and ''Garetz'' formulas. IBU's for light beers are generally in the 10-20 range, while dark flavorful beers such as stouts may have an IBU as high as 50. Some barley wines have IBU values of 100 or more to offset the extreme malty sweetness of the beer. See the [[Beer Styles]] BJCP guide for some typical IBU ranges for different styles of beer.

	===Bittering Oils===		===Bittering Resins and Oils===
	Bittiness in beer is provided by ~~oils~~ released by the hops. The ~~bittering oils~~ of the hops are isomerized (rearranged) during the boil. Insoluable alpha acids (α-acids) are isomerized by the boil into more soluble and stable alpha acids. As the boil time increases, the bitterness released also increases. These alpha acids provide the majority of the bitterness in finished beer, as estimated by the Alpha Acid Units (AAUs). A second ~~component~~ called beta acid also provides some bitterness. ~~Additional~~ compounds ~~in hops~~ provide ~~both~~ aroma and preservative qualities.		Bittiness in beer is provided by resins released by the hops. The battering resins of the hops are isomerized (rearranged) during the boil. Insoluable alpha acids (α-acids) are isomerized by the boil into more soluble and stable alpha acids. As the boil time increases, the bitterness released also increases. These alpha acids provide the majority of the bitterness in finished beer, as estimated by the Alpha Acid Units (AAUs) or Homebrew Bitterness Units (HBU's). A second resin called beta acid also provides some bitterness. The amount of bettering coming from beta acids depend on the degree of oxidation, or, how much oxygen the hops have been exposed to over time.

			Hop oil compounds provide flavor, aroma and preservative qualities. They are soluble in water and easily boiled off. Dry hopping will allow one to impart these properties without the risk of boiling-them-off.
