How much alcohol for 25 wedding guests?

For 25 adult guests over about 5 hours with an average drinking profile and a 50/35/15 wine, beer, and spirits split, the estimate below gives a starting bar list. Small weddings are sensitive to known guest preferences, so adjust for non-drinkers and venue rules.

How to use this guest-count example

This example uses 25 adult guests, 5 hours of bar service, and a average drinking profile. The calculator produces a shopping-list estimate, so the result should be reviewed against the actual schedule, guest mix, and venue rules.

• Count adult guests who may drink alcohol, not the total invitation count.
• Use the hours when drinks are served, not automatically the full venue hire period.
• Change the profile if the group is clearly lighter or heavier than average.

Before turning it into an order

The example splits 165 estimated drinks into wine, beer, and spirits using the entered percentages. Convert the rounded bottles and cans into supplier case sizes before buying.

• Plan water, soft drinks, alcohol-free options, ice, glassware, and garnishes separately.
• Ask whether unopened bottles or cases can be returned.
• Follow venue rules, licensing requirements, and responsible-service limits.
