What is considered a serving of alcohol?

A standard serving of alcohol typically contains about 14 grams of pure alcohol. This is generally equivalent to one 12-ounce beer (with around 5% alcohol), one 5-ounce glass of wine (about 12% alcohol), or a 1.5-ounce shot of distilled spirits (approximately 40% alcohol). These measurements can vary by country and specific beverage types, but they provide a useful guideline for understanding alcohol consumption.
