If you pour six glasses from the same bottle each glass contains approximately 1.3 standard drinks or 13 grams of pure alcohol. Simple! Because wines have different amounts of alcohol in them, not all bottles of wine will contain eight standard drinks.
Keeping this in view, how many glasses of wine can you drink and drive?
As a rule of thumb, two pints of regular-strength lager or two small glasses of wine would put you over the limit. But this isn't a catch-all rule. Factors like your weight, sex, metabolism and how much you've eaten all contribute to how your body processes alcohol, so everyone has different limits.
How much is a serving of wine?
Usually this will be around four or five ounces. If you like to enjoy a glass of wine every night, then make sure the bottle of wine lasts you five nights; there are about five glasses of five-ounce pours in every 750 mL bottle of wine.
