Butyric acid is an acid produced by bacteria that produce syrup for beer, or can be produced during wort production. When the content of butyric acid in beer exceeds 2-3 mg/litre, the beer tastes like metamorphic milk or rotten butter. To avoid this result, acidic sputum should be kept above 90 °F and have minimal contact with oxygen.
Butyric acid (/ ˈ b j uː t ɪ r ɪ k /; from Ancient Greek: βούτῡρον, meaning "butter"), also known under the systematic name butanoic acid, is a straight-chain alkyl carboxylic acid with the chemical formula CH 3 CH 2 CH 2 COOH. It is an oily, colorless liquid with an unpleasant odor.

The majority of compounds in beer come from the metabolic activities of plants and yeast and so are covered by the fields of biochemistry and organic chemistry. [1] The main exception is that beer contains over 90% water and the mineral ions in the water (hardness) can have a significant effect upon the taste. [2]
The word "butyl" is derived from butyric acid, a four-carbon carboxylic acid found in rancid butter. [1] The name "butyric acid" comes from Latin butyrum, butter. Subsequent preferred IUPAC names for alkyl radicals in the series are simply named from the Greek number that indicates the number of carbon atoms in the group: pentyl, hexyl, heptyl ...
This is a list of alcoholic drinks. An alcoholic drink is a drink that contains ethanol, commonly known as alcohol. Alcoholic drinks are divided into three general classes: beers, wines, and distilled beverages. They are legally consumed in most countries, and over one hundred countries have laws regulating their production, sale, and ...
