About this calculator

Plan on roughly one drink per guest per hour, weighted toward the first two hours. Split that across wine, beer, and spirits by your crowd's preference and convert to bottles and cases.

FAQ

How many drinks are in a bottle?

A 750ml wine bottle pours about five 5 oz glasses. A 750ml spirits bottle yields about sixteen 1.5 oz pours.

Should I buy extra?

Buy on the high side where the retailer takes returns on unopened cases — a common arrangement for weddings — so overbuying costs nothing but a trip back.

Accuracy and limitations

  • Estimates assume standard, average conditions — local rules, pricing, and materials vary.
  • Results are rounded for readability; add a buffer before ordering, booking, or committing.
  • Double-check anything with a real cost attached against a local quote.
