This is a term related to Alcohol by Volume which is abbreviated as ABV or alc/vol. It is a common measure of the amount of alcohol present in any given volume of alcoholic drink and is expressed in alcohol percentage. It shows how much alcohol (ethanol – chemical compound) content there is in a beverage.
A Unit of alcohol is used to indicate the actual alcohol quantity within a volume of alcoholic substance and to provide information on total alcohol consumption. One unit of alcohol contains 10 milliliters or 8 grams of pure alcohol. Typical servings of drinks usually contain 1-3 units of alcohol.
Gravity in alcoholic beverages refers to specific gravity or relative density of the substance (wort or must) compared to the density of reference substance usually water. Gravity is measured by hydrometer. The density of a wort or must is influenced by their sugar content. The amplitude between the original (gravity before fermentation) and final gravity (measured when fermentation completes) indicates how much sugar has changed into alcohol and hence the bigger the difference, the more alcohol content present and the stronger the drink.
Oxygen exposure to wine improves its taste because it softens the acerbic tannins and releases the fruit and floral aromas. So this is why wine is poured into decanters and wide wine glasses.
The Units utilized for wine volume are the same as some standard volume units such as ounces, liters, milliliters. The names of the containers are also used for units for wine volumes such as glass and bottle.
