Pour size matters

Restaurant and home glasses are often bigger than 5 fl oz. Our calculation: an 8 fl oz pour of 12% wine holds about 0.96 fl oz of pure alcohol, or about 1.6 standard drinks.

Wine ABV Amount Standard drinks
Table wine 12% 5 fl oz 1
Fortified wine (sherry, port) 17% 3-4 fl oz 1
Bottle of table wine 12% 750 ml 5

Wine strength varies

NIAAA’s numbers are typical, and actual alcohol content can vary widely. Check the bottle label. A 15% wine in a 5 fl oz glass has more alcohol than the standard, about 1.25 drinks (our calculation).

Use the standard drink calculator for your pour. Ask a doctor about alcohol and your health.
