About eight 3 oz toast pours per 750 ml bottle
85 champagne drinkers from 100 total guests
85 base pours + 10% buffer = 94
8 pours per bottle for this service style

Champagne vs. Sparkling Wine: What to Choose
True Champagne
Sparkling wine produced in the Champagne region of France under its applicable designation rules.
Evaluate:
- The exact bottle alongside the menu
- Delivered price and available formats
- Corkage, chilling and service requirements
Before ordering:
Taste the exact bottle and confirm vintage, size, stock and venue corkage.
Sparkling Wine Alternatives
Distinct sparkling-wine styles available across a wide range of prices.
Compare like with like:
Record the producer, wine, vintage, bottle size and delivered price.
Pro tip: Taste options at your target price before ordering by the case. Prosecco, Cava and Champagne have different flavor profiles, so the best choice is the one that fits your menu and guests.

Include tax, delivery, chilling, glassware, service and any venue corkage.

Frequently Asked Questions
How many bottles of champagne do I need for a wedding toast with 100 guests?
If all 100 guests receive a half-glass toast, plan 13 bottles without a buffer or about 14 with a 10% buffer. One full glass per guest needs about 17 bottles, or 19 with the buffer. Reduce the count for guests who will skip champagne.
How many glasses of champagne are in a bottle?
A standard 750ml bottle yields about 6 full 4oz pours or 8 smaller 3oz toast pours in this calculator. A 1.5L magnum holds twice the volume; compare its current price and handling requirements with two standard bottles.
Should I use real Champagne or sparkling wine for my wedding?
That depends on taste, menu and budget. Champagne refers to sparkling wine from the Champagne region of France; Prosecco, Cava and domestic sparkling wines offer different styles at many price points. Taste candidates before ordering cases and confirm the venue's corkage policy.
When should I serve champagne at my wedding?
Possible service moments include the toast, cocktail-hour arrivals, cake cutting, dessert, or full reception service. A single toast uses fewer sparkling-wine pours than continuous service, so it can be easier to fit into a limited budget.
Do I need to provide champagne for non-drinkers?
No. Use the calculator's non-drinker control based on your actual guest list, and include children or guests who prefer their current drink. Offer sparkling cider, sparkling water or another alcohol-free toast option.
How do I keep champagne cold for a wedding?
Follow the producer or venue guidance for the bottles you select. Coordinate refrigerator and cooler capacity in advance, use an ice-and-water bath when rapid chilling is appropriate, and keep unopened backup bottles cold until service.
