Wine Calculator

How many bottles of wine should you buy for a party or holiday dinner? Enter your guests, how many of them drink wine, party length and pour size. Results use a common rule of thumb and are rounded up to whole bottles.

Rules used

• Glasses: 2 per wine drinker in the first hour, 1 per hour after.
• 750 ml bottle = 25.36 fl oz. Magnum (1.5 l) = 2 bottles. Case = 12 bottles.
• Red/white split is applied to bottles (red rounded up, white/rose gets the rest). Sparkling for a toast: see the champagne calculator.
