How many "drinks" are in a bottle of wine?
A typical 25-ounce (750 ml) bottle of table wine holds about 5 "standard" drinks, each containing about 5 ounces. This serving size of wine contains about the same amount of alcohol as a 12-ounce regular beer or 1.5 ounces of 80-proof spirits.
Get to know what 5 ounces looks like by measuring it out at home. That way you can estimate how many standard drinks you're being served in a restaurant or bar that uses large glasses and generous serving sizes.
