How much alcohol for 125 wedding guests?

By Forever Farrah Published 2026-10-19.

For 125 guests over a five-hour bar, buy about 68 bottles of wine, 206 beers and 9 bottles of spirits, plus 25 of sparkling for the toast.

For 125 wedding guests and a five-hour bar, plan about 688 drinks: roughly 68 bottles of wine (about 6 cases), 206 bottles or cans of beer and 9 bottles of spirits. Add 25 bottles of sparkling wine if everyone gets a glass for the toast. That assumes one drink per guest per hour, a 10% buffer, and a split of half wine, 30% beer and 20% spirits.

How the 688 drinks are worked out

125 guests × 5 hours × 1 drink an hour × 1.1 buffer = 688 drinks.

Split by what people drink, that is 344 glasses of wine, 206 beers and 138 spirit measures. A 750 ml bottle pours about 5 glasses of wine or about 16 measures of spirits, and every bottle count is rounded up.

If your guests drink differently

The split matters as much as the total. Shift it toward what your guests actually order.

Ways to buy less without running out

• Not everyone drinks. If a quarter of your guests won't, take a quarter off every number above, or set it in the calculator below.
• Ask about sale or return. Many shops take back unopened bottles, so you can buy to the top of the range.
• Close the bar during dinner if wine is on the tables, and count the dinner wine once.
• Ask your venue what is included. Some packages already cover the toast or a house wine.
