What is This Tool
The Wedding Alcohol Calculator is a sophisticated planning utility designed to eliminate the stress of beverage logistics for your big day. By analyzing your guest list size, event length, and the general "vibe" of your attendees, it provides a precise inventory list for beer, wine, and spirits. Whether you are hosting an intimate champagne brunch or an all-night open bar extravaganza, this tool ensures you have enough to keep the toasts flowing without overspending on excess inventory that might never be opened.

Frequently Asked Questions
What is considered a "Standard" drink for this calculation?
We define a standard drink as one 12oz beer, one 5oz glass of wine, or a 1.5oz shot of spirit. Our tool bases its bottle counts on these serving sizes.
How many glasses of wine are in a standard 750ml bottle?
A standard 750ml bottle provides approximately 5 glasses of wine. Our calculator automatically handles this math to give you a bottle count.
Should I include non-drinkers in the guest count?
For the most accurate result, only include the number of guests who you expect to drink alcohol. You should plan soft drinks and water separately.
Does the time include the cocktail hour?
Yes, you should include the entire duration that the bar is accessible to guests, including the transition between ceremony and dinner.
Can I use this for a champagne toast?
This calculator covers general consumption. For a specific "Champagne Toast" where everyone gets a glass, add 1 bottle of sparkling wine for every 8-10 guests.
How many drinks does a 750ml bottle of liquor provide?
A 750ml bottle contains roughly 16 to 17 standard 1.5oz pours. The tool uses this ratio to calculate your spirit inventory.
Advanced Tips
- Know Your Crowd - If your guests are primarily craft beer enthusiasts, reduce the wine count by 10% and increase beer by 10%.
- Seasonal Adjustments - For summer outdoor weddings, white wine and rosé are more popular. In winter, guests tend to prefer red wine and spirits.
- The Signature Drink Hack - If serving two signature cocktails, spirits consumption often rises by 15-20% as guests try both options.
- Champagne Strategy - Many guests take a glass for the toast but don't finish it. Consider pouring half-glasses for toasts to reduce waste.
- Check Local Laws - Some jurisdictions have "corkage fees" or specific rules about bringing your own alcohol; factor these into your final budget.
- Overbuy the Staples - It is better to have 2 extra cases of beer than to run out. Focus your "extra" budget on items with a long shelf life.
