Types of Alcohol - List of Drinks By Alcohol Content ...

Feb 24, 2022 Rum, a distilled drink made from fermented sugarcane or molasses, has a typical alcohol concentration of 40% ABV. Some rum is “overproof,” meaning that it has alcohol concentration of at least 57.5% ABV. Most overproof rum exceeds this minimum, usually reaching 75.5% ABV, which is equivalent to 151 proof. Tequila Tequila is a type of liquor.

Sep 06, 2020 the alcohol content. For fermented beverages, like wine and beer, the alcohol content is expressed in percent by volume, while for distilled liquors the alcohol content is usually given in terms of a “proof” rating. Proof is equal to twice the percent by volume of alcohol. Distillation has many other applications.

An analysis of alcohol breath tests results with portable ...

There is a perceived tradeoff between the ease of measuring alcohol in the body and the accuracy of the result. Direct tests of blood alcohol concentrations are considered the most accurate, desktop stationary breath testers based on electro-chemical infra-red technology are slightly less accurate, but accepted for evidentiary purposes in most jurisdictions, and quick …
