Plan beer, wine, and spirits for a wedding reception

A wedding alcohol calculator estimates how much beer, wine, and spirits to buy from the guest count, reception length, expected non-drinker share, beverage mix, and a planning buffer. It is designed to help with ordering and budgeting, not to replace venue rules, bartender judgement, or local alcohol service law.

About this calculator

Reviewed 2026-03-20

Methodology

The planner estimates drink demand from a guest-count model, a selectable pace assumption, beverage shares, a toast add-on, and standard package assumptions of 24 beers per case, 5 glasses of wine per 750 mL bottle, and about 17 spirit servings per 750 mL bottle.

Limitations

Actual consumption varies with weather, demographics, bar service style, and the rest of the menu.
The package assumptions are planning shortcuts and may differ from venue pours or local package sizes.
The result is not legal, licensing, responsible-service, pregnancy, medication, or driving guidance.

Disclaimer

Use this tool for event planning only. Confirm the final order with your venue, caterer, bartender, or drinks supplier, and follow all local alcohol-service rules and health advice.

How the planner estimates drinks

The calculator starts by estimating how many guests are likely to drink, based on the total guest list and your non-drinker percentage. It then applies a pace model for the reception: light, moderate, or lively. Each pace assumes a stronger first hour and a steadier rate for the remaining hours, which reflects how many receptions start with arrival drinks, then settle into dinner service and dancing.

After that, the total drinks are split across beer, wine, and spirits according to the mix you set. A toast option adds one extra wine-equivalent serving per drinking guest, and the safety buffer helps cover strong pours, waste, late additions, and the reality that demand is rarely perfectly even across drink types.

What a bottle count really means

Bottle counts are only a planning shorthand. Beer is counted in single serves and grouped into cases of twenty-four. Wine is estimated at roughly five glasses per 750 mL bottle. Spirits are estimated from standard 1.5 oz / 44 mL pours, which works out to about seventeen standard mixed-drink servings per 750 mL bottle.

Your venue, caterer, and bartending format can change the real number materially. Open bars, heavy cocktail menus, hot-weather outdoor weddings, and crowds that drink mainly one category can all shift demand away from an average planning model. That is why the output should be treated as a starting sheet for ordering conversations, not a final compliance or service plan.

Frequently asked questions

How much alcohol should I buy per guest for a wedding?

There is no single universal number because wedding length, crowd behaviour, weather, and menu all matter. This planner uses a drinks-per-hour model so you can adjust for a lighter lunch reception versus a longer evening celebration instead of relying on one flat per-guest rule.

Should I include a safety buffer?

Usually yes. A modest buffer helps cover uneven demand, broken bottles, strong pours, and last-minute attendance changes. Many couples would rather have a small surplus than run out in the final hour of the reception.

Does this calculator tell me what is legally safe to serve?

No. It is a stock-planning tool only. Venue policies, local alcohol law, bartender staffing, and responsible-service practices all override the calculator output.
