You are watching: How many servings per bottle of wine

How much wine is “enough” alcohol for your dinner party? here’s a comfortable drink calculator because that you—actually, it’s solely a alcohol calculator. Most people would say the the dinner is the many important component of a dinner party, but I would certainly argue that having enough wine.

A bottle of alcohol is 750 milliliters, which works out to around 25 ounces. The argued serving size of alcohol is five ounces, which would mean each party has five glasses. If you want to pole to the math, that is perfectly fine, although, personally, i don’t think five ounces is a glass the wine. Ns think it’s a joke. Who pours specifically five ounces the wine? No one. If you occupational from the five-glasses-per-bottle logic, you nearly always come up short. According to my very professional opinion, a 750-ml party of wine functions out come be about four glasses that wine, and two chugs right from the bottle you room awarded together the dinner party host.
