Wine Bottle Servings Calculator

A standard 750 ml bottle holds five 150 ml pours, which is the usual 5 oz serving. Larger or smaller pours change this, so a heavy 200 ml pour gives only three full glasses per bottle.

Multiply guests by glasses per guest to get total glasses, then divide by glasses per bottle and round up. For 30 guests at 3 glasses that is 90 glasses, or 18 bottles at a standard pour.

A common planning figure is two to three glasses per guest over a two to three hour event, with the first hour heaviest. Adjust up for a long celebration or down for a lunch.

You cannot buy a fraction of a bottle, so it rounds up to make sure there is enough. It also counts only whole pours per bottle, so leftover wine that is less than a full glass is not assumed to serve anyone.

Yes. Set the bottle size to 1500 ml for a magnum, and use a smaller pour such as 120 ml for sparkling wine, which is typically served in shorter measures than still wine.
