An 80 proof bottle of any alcohol has 40% alcohol by volume. The rest is mostly water.
Alcohol by volume
Alcohol proof is a measure of how much alcohol (ethanol) is contained in an alcoholic beverage. The term was originally used in the United Kingdom and was defined as 7/4 times the alcohol by volume (ABV). The UK now uses the ABV standard instead of alcohol proof. In the United States, alcoholic proof is defined as twice the percentage of ABV.
The measurement of alcohol content and the statement of this content on the bottle labels of alcoholic beverages is regulated by law in many countries. The purpose of the regulation is to provide pertinent information to the consumer.
Alcohol by volume (abbreviated as ABV, abv, or alc/vol) is a standard measure of how much alcohol (ethanol) is contained in an alcoholic beverage (expressed as a percentage of total volume). It is defined as the number of millilitres of pure ethanol present in 100 millilitres of solution at 20 °C. The number of millilitres of pure ethanol is the mass of the ethanol divided by its density at 20°C, which is 0.78924 g/ml. The ABV standard is used worldwide.
In some countries, alcohol by volume is referred to as degrees Gay-Lussac (after the French chemist Joseph Louis Gay-Lussac), although there is a slight difference since Gay-Lussac used 15°C.
An alcoholic beverage is a drink that contains ethanol. Alcoholic beverages are divided into three general classes for taxation and regulation of production: beers, wines, and spirits (distilled beverages). They are legally consumed in most countries around the world. More than 100 countries have laws regulating their production, sale, and consumption. Beer is the third most popular drink in the world, after water and tea.
Alcoholic beverages have been consumed by humans since the Neolithic era; the earliest evidence of alcohol was discovered in Jiahu, dating from 7000–6600 BC. The production and consumption of alcohol occurs in most cultures of the world, from hunter-gatherer peoples to nation-states.
Neutral grain spirits
A distilled beverage, spirit, or liquor is an alcoholic beverage containing ethanol that is produced by distilling (i.e., concentrating by distillation) ethanol produced by means of fermenting grain, fruit, or vegetables. This excludes undistilled fermented beverages such as beer, wine, and cider. Types of distilled beverages include Vodka, gin, baijiu, tequila, rum, whisky, brandy, slivovitz and soju.
The term hard liquor is used in North America to distinguish distilled beverages from undistilled ones (implicitly weaker).
Crystal Head Vodka
A rectified spirit, also known as rectified alcohol, grain alcohol, or neutral spirit, is highly concentrated ethanol which has been purified by means of repeated distillation, a process that is called rectification. It typically contains 95% alcohol by volume (ABV). Rectified spirits sold on the consumer market are used in mixed drinks, in the home production of liqueurs, for medicinal purposes, and as a household solvent. Rectified spirits are also produced by distillers for dilution and mixing with more traditional distilled beverages to produce inexpensive liquor.
The purity of rectified spirit has a practical limit of 95.6% ABV (191.2 US proof) when produced using conventional distillation processes, because a mixture of ethanol and water becomes an azeotrope at this concentration.
Crystal Head Vodka is an additive-free vodka manufactured by Globefill Inc. in Newfoundland and Labrador, Canada. It was conceived of and founded by actor Dan Aykroyd and artist John Alexander in 2007.
The vodka is quadruple-distilled and seven times filtered, the final 3 filtrations through Herkimer diamond crystals. It is additive-free, gluten-free, and kosher certified. The product is packaged in a cardboard box, sold in a clear glass bottle in the shape of a human skull that has a wooden bottle closure. The bottle was designed by artist John Alexander and is manufactured by Milan-based glass-manufacturer Bruni Glass.
