Wedding Wine Quantity Calculator
Estimate total bottles, style split, and case count for your event based on practical serving assumptions.
Use this before ordering cases
Wedding wine planning often fails at the extremes: too little wine creates stress, while too much ties up budget. This calculator turns guest count, drinking share, event length, and wine mix into bottle and case estimates.
- Adjust the drinking percentage for your actual guest list rather than using a generic average.
- Separate sparkling, white, rose, and red if your event has distinct reception and meal phases.
- Check venue corkage, return policies, and delivery timing before committing to the order.
Turning a guest count into a wine order
The guest count is only the starting point. A daytime reception, a winter dinner, a venue with a full bar, and a crowd of enthusiastic wine drinkers can all produce very different bottle counts for the same number of people.
Use the calculator to build a base order, then adjust for the event you actually have. It is usually better to separate sparkling, white, red, and non-alcoholic needs than to rely on one large average. If the retailer offers sale-or-return, model the order generously but check the return conditions before buying.
- Allow for speeches, dinner pace, and the bar opening time.
- Round up to full cases only after checking return terms.
- Keep a small reserve for service delays or unexpected extra guests.
Plan for behaviour, not just headcount
Guest count is the starting point, but wedding wine use depends on schedule, weather, food style, transport, non-drinkers, and whether there is a full bar. Use the result as a first order estimate, then adjust for the actual rhythm of the day.
Best use
Building an initial order split between sparkling, white, rose, and red.
Do not skip
Sale-or-return terms, venue corkage, glass size, and delivery timing.
How It Works
This calculator estimates total bottles needed from guest count and drinking pace assumptions.
- Enter guest count, percentage of wine drinkers, and service duration.
- Set average glasses per hour and desired red/white/sparkling split.
- Review total glasses, bottles, cases, and estimated bottle budget.
Worked example
Take a 100-guest wedding where 80% of guests are expected to drink wine across five hours of service. At 0.8 glasses per person per hour, the event lands at a very different bottle count from the old rule-of-thumb advice to “just buy a bottle per guest and hope for the best”.
This calculator is meant to replace guesswork with adjustable assumptions. It is especially useful when your event has a known red-white-sparkling split or when part of the guest list will be drinking beer, cocktails, or no alcohol at all.
Where estimates go wrong
Most over-ordering happens because couples buy for the total guest list instead of the likely wine-drinking subset. Most under-ordering happens because service length, reception pours, and sparkling wine are not planned separately.
Use this tool for bottle count and rough budget, then compare the result with venue package terms, corkage rules, and sale-or-return options before you place an order.
FAQ
How many glasses does one bottle represent?
The default model uses about five 150 ml pours per 750 ml bottle.
Should I add a safety margin?
Yes. Many events add a small buffer to avoid running out near the end of service.
Can I model only one wine style?
Yes. Set one style share to 100% and the others to 0%.
