In particular, large quantities of neutral alcohol are distilled from wine and by-products of wine production (pomace, lees [4]). A product made from grain is "neutral grain spirit", while a spirit made from grapes is called "grape neutral spirit" [5] or "vinous alcohol". [6] These terms are commonly abbreviated as either GNS or NGS. [7] [8] [9]
For example, ordinary vodka, gin, rum and tequila have an alcohol concentration typically around 40% alcohol by volume (80 proof), and liqueurs are typically around 20% alcohol (40 proof). [ 6 ] Everclear is also used as a household "food-grade" cleaner, disinfectant, or stove fuel alcohol because its fumes and odor are less offensive than ...
There are a number of empirical formulae which brewers and winemakers use to estimate the alcohol content of the liquor made. [ citation needed ] Specific gravity is the density of a liquid relative to that of water, i.e., if the density of the liquid is 1.05 times that of water, it has a specific gravity of 1.05.
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 ...
Because the flash point of alcohol is highly dependent on temperature, 100 proof defined this way ranges from 20% at 36 °C (97 °F) to 96% at 13 °C (55 °F) alcohol by weight; at 24 °C (75 °F) 100 proof would be 50% ABW. [2] Another early method for testing liquor's alcohol content was the "gunpowder method".
Alcoholism reduces a person's life expectancy by around ten years [46] and alcohol use is the third-leading cause of early death in the United States. [43] Consumption of alcohol in any quantity can cause cancer. Alcohol causes breast cancer, colorectal cancer, esophageal cancer, liver cancer, and head-and-neck cancers. The more alcohol is ...
Korenwijn (grain wine) and the oude (old) style of Geneva gin or Holland gin represent the most prominent gins of this class. [ 31 ] Column distilled gin evolved following the invention of the Coffey still , and is produced by first distilling high proof (e.g. 96% ABV) neutral spirits from a fermented mash or wash using a refluxing still such ...
Whereas a single pot still charged with wine might yield a vapour enriched to 40–50% alcohol, a column still can achieve a vapour alcohol content of 96%; an azeotropic mixture of alcohol and water. Further enrichment is only possible by absorbing the remaining water using other means, such as hydrophilic chemicals or azeotropic distillation ...
