Estimate how much beer, wine, and liquor to buy for your wedding or event based on guest count, event length, and drinking preferences.
Frequently Asked Questions
How many drinks does one guest typically have?
A common rule of thumb is one drink per guest per hour for a mixed open bar, adjusted for how many guests actually drink alcohol.
How is a bottle of wine measured in drinks?
A standard 750ml bottle of wine yields about 5 glasses, and a 750ml liquor bottle yields about 17 standard cocktail pours.
Should I buy more than the calculator suggests?
It's wise to add a 10-15% buffer, especially for popular items, since running out is worse than having leftovers.
