Which drinks contain the same amount of alcohol?

Each of these drinks contains approximately the same amount of pure alcohol, which is about 0.6 ounces (or 17.7 milliliters). It's important to note that different types of alcoholic beverages have different alcohol concentrations. Wine typically has an alcohol content of around 12% to 15%, beer is usually around 4% to 6% alcohol by volume, and 80-proof liquor is 40% alcohol by volume (ABV). 100-proof liquor is 50% ABV.
Therefore, to achieve the same amount of alcohol, you would need larger quantities of lower-alcohol beverages (such as wine and beer) compared to smaller quantities of higher-alcohol beverages (such as 80-proof or 100-proof liquor).
