WebBeer contains a great number of esters of aliphatic fatty acids. Ethyl acetate is the principal one, occurring at 10–30 mg/l (with values up to 69 mg/l), while isopentyl acetate has been found at 1–7.8 mg/l. Alpha acids (α acids) are a class of chemical compounds primarily of importance to the production of beer. They are found in the resin glands of the flowers of the hop plant and are the source of hop bitterness. Alpha acids may be isomerized to form iso-alpha acids by the application of heat in solution.
