Liquor (also hard liquor, hard alcohol, spirit, or distilled drink) is an alcoholic drink produced by distillation of grains, fruit, or vegetables that have already gone through alcoholic fermentation. The distillation process purifies the liquid and removes diluting components like water, for the purpose of increasing its proportion of alcohol content (commonly expressed as alcohol by volume, ABV). As liquors contain significantly more alcohol, they are considered "harder" – in North America, the term hard liquor is used to distinguish distilled alcoholic drinks from non-distilled ones.
As examples, this term does not include beverages such as beer, wine, mead, sake, or cider, as they are fermented but not distilled. These all have a relatively low alcohol content, typically less than 15%. Brandy is a fortified wine produced by the distillation of wine, and has an ABV of over 35%. Other examples of liquors include vodka, baijiu, gin, rum, tequila, mezcal, and whisky. (Also see list of alcoholic drinks, and liquors by national origin.)
