Alcohol strength is typically measured by Alcohol By Volume (ABV), which is the percentage of pure alcohol in a drink. Spirits or liquor are considered strong alcoholic drinks, generally ranging from 37.5% ABV to over 50% ABV. For example, vodka, gin, rum, whiskey, and tequila commonly have ABVs between 36% and 50%, with some like tequila reaching up to about 51% ABV. In contrast, beer usually has an ABV of 4-8%, and wine generally ranges from 14-16% ABV, with fortified wines reaching up to 24% ABV. Because spirits have a much higher concentration of alcohol compared to beer or wine, they are regarded as strong alcoholic beverages. The effects of alcohol depend on how much is consumed, the speed of consumption, tolerance, and other factors, not just the strength of the drink itself.
