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.
This means that the beer has smaller bubbles and a more creamy and stable head. [6] These less soluble inert gases give the beer a different and flatter texture. In beer terms, the mouthfeel is smooth, not bubbly like beers with normal carbonation. Nitro beer (for nitrogen beer) could taste less acidic than normal beer. [7]

I believe a chart is better (even if less precise) than a list or a table because points out clearly the logical links between the different kinds. If you want to make a list as well, you are absolutely welcome, but I still find the chart approach more useful. Date: 24 December 2006: Source: own work
Clostridium butyricum is a strictly anaerobic endospore-forming Gram-positive butyric acid–producing bacillus subsisting by means of fermentation using an intracellularly accumulated amylopectin-like α-polyglucan (granulose) as a substrate. It is uncommonly reported as a human pathogen and is widely used as a probiotic in Japan, Korea, and ...
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 .
The categories are varied and include processes or ingredients not usually regarded as defining beer styles in themselves, such as cask ale or gluten-free beer. [2] [3] [4] Beer terms such as ale or lager cover a wide variety of beer styles, and are better thought of as broad categories of beer styles.
