Brewing yeasts contribute positively to beer mouth-feel by producing carbon dioxide and foam bubbles. The impact of yeasts on beer taste varies with the yeasts involved in beer fermentation. In the spontaneous fermentation of acidic beers such as lambics, the mn-Saccharomyces brettanomyces yeasts can ferment malto-oligosaccharides that...

Carbon dioxide is responsible to a substantial extent for the refreshing value and stability of beer. CO2 is 0.36-0.44% in bottom fermented beers, while in Weiss beer the CO2 content is up to 0.6-0.7%. A CO2 content below 0.2% gives flat and dull beers. Apart from small amounts of lactic, acetic, formic, and succinic acids, beer contains 9,10,13- and 9,12,13-tri-hydroxyoctadecenoic acid. In fact, 9.9 2.1 mg/1 were found in five types of beer and 9(S), 12(S), 13(S)-trihydroxy-10(E)-octadecenoic acid was the main compound and accounted for 50-55% of the 16 stereoisomers. The pH of beer is between 4.7 (dark, strong beer) and 4.1 (Weiss beer). 

A disorder in which (1) the skin has a bronzelike hue, and (2) there is a loss of function of the liver and/or the pancreas. It results from the abnormal accumulation of iron in these tissues due to some unknown disorder of iron metabolism, or to the absorption of a great excess of iron. One of the conditions under which a great excess of iron may be absorbed is the consumption of iron in alcoholic beverages, such as the beer made by the Bantu tribes of Africa. (The Bantu tribes brew their acid beer in iron pots.) Also, iron overload can be caused by high intakes of iron supplements.

PracticaUy, the core microbiota is responsible for the major characteristics of acidic beer fermentation processes. The application of novel techniques and exhaustive studying of this relatively unknown fermentation process give further insights into the complexity of lambic beer production processes (Spitaels et al. 2014a, 2015b).
