Wine Bottles Per Guest Calculator
Enter your guest count and how long the event runs to see how many bottles to buy.
How this works
A standard 750ml wine bottle holds about 25 ounces, which pours into roughly five 5-ounce glasses. Event planners commonly estimate one glass per guest per hour of service. Multiplying guests × hours gives total glasses, which converts to bottles at 5 glasses each.
Source: Based on the standard catering estimate of one 5-ounce glass of wine per guest per hour, with 5 glasses per 750ml bottle.
Frequently asked questions
How many glasses of wine are in a standard bottle?
A standard 750ml bottle holds about 25 ounces, which pours into roughly five 5-ounce glasses at a typical serving size.
Should I split bottles between red and white wine?
A common approach is roughly half red, half white, adjusted for the season and menu — more white for a summer or seafood-heavy event, more red for a winter or heavier-menu event.
Does this account for guests who don't drink wine?
No — this calculator assumes all guests are drinking wine for the full event length. If only some guests drink wine, reduce the guest count by that share, or check the Wedding Alcohol Calculator for a mixed-bar breakdown.
