The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process.
In ethanol fermentation, one glucose molecule is converted into two ethanol molecules and two carbon dioxide (CO 2) molecules. [11] [12] It is used to make bread dough rise: the carbon dioxide forms bubbles, expanding the dough into a foam. [13] [14] The ethanol is the intoxicating agent in alcoholic beverages such as wine, beer and liquor. [15]
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
Liquor bottled with added sugar and flavorings, such as Grand Marnier, amaretto, and American schnapps, are known instead as liqueurs. [8] Liquor generally has an alcohol concentration higher than 30% when bottled, and before being diluted for bottling, it typically has a concentration over 50%.
Weighing hops. The chemical compounds in beer give it a distinctive taste, smell and appearance. 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 natural occurrence of fermentation means it was probably first observed long ago by humans. [3] The earliest uses of the word "fermentation" in relation to winemaking was in reference to the apparent "boiling" within the must that came from the anaerobic reaction of the yeast to the sugars in the grape juice and the release of carbon dioxide.
Mead (/ m iː d /), also called hydromel, is an alcoholic drink made by fermenting honey with water, sometimes with various fruits, spices, grains, or hops. The alcoholic content of mead may range from as low as 3% ABV to more than 20%. The defining characteristic of mead is that the majority of the drink's fermentable sugar is derived from honey.
