How Much Alcohol Do You Need for a Wedding? (2026 Guide)
Running out of drinks at a wedding is every couple’s nightmare, and overbuying by hundreds of dollars is a close second. The good news: one simple rule of thumb, your guest count, and your drink split will get you within a few bottles of the right order.
Before you place an order, run your numbers through the free wedding alcohol calculator — enter your guests, reception hours, and beer, wine, and spirits split, and it gives you bottles, cases, and total cost in seconds.
How much alcohol do you need for a wedding?
Plan on one drink per guest per hour of bar service, multiplied by the share of guests who actually drink. For a 100-guest wedding with 80% drinkers and a 4-hour reception, that is 320 drinks: 26 bottles of wine, 6 cases of beer, and 4 bottles of spirits at a 40/40/20 split, costing about $654 at typical retail prices.
The one-drink-per-hour rule is the standard starting point used by wedding planners and alcohol calculators alike. Some planners use two drinks in the first hour and one per hour after, which gives a slightly higher total.
How many bottles of wine do you need for a wedding?
A 750 ml bottle of wine pours about 5 glasses, so divide your wine drinks by 5 and round up. For a 100-guest, 4-hour wedding with 80% drinkers and a 40% wine share, that is 128 wine drinks, or 26 bottles. If wine is your only drink option, the same wedding needs 64 bottles.
Split the wine roughly evenly between red and white, leaning toward white and rosé in summer and red in cooler months. For a champagne toast, budget one bottle per six guests on top of your regular wine — 17 bottles for 100 guests.
How much beer do you need for a wedding?
Beer is bought by the case of 24, so divide your beer drinks by 24 and round up. A 100-guest, 4-hour wedding with 80% drinkers and a 40% beer share needs 128 beer drinks, or 6 cases. For a beer-heavy crowd, raise the beer percentage — younger crowds and backyard weddings typically drink more beer and cocktails and less wine.
Buying beer by the case usually saves 10 to 15% compared with buying individual six-packs, and unopened cases are easy to return if your supplier allows it. Ask about the return policy before you order.
How many bottles of spirits do you need for a wedding?
A 750 ml bottle of spirits gives about 16 standard 1.5 oz pours, so divide your spirit drinks by 16 and round up. The same 100-guest example at a 20% spirits share needs 64 spirit drinks, or 4 bottles. Split those bottles across two to four types — vodka and whiskey cover most cocktail orders.
Spirits are the most expensive part of the bar per drink, which is why a full bar costs much more than a beer-and-wine bar. If budget is tight, offering one or two signature cocktails instead of a full spirits range keeps the cocktail experience while limiting the bottles you must stock.
How much does wedding alcohol cost on average?
At typical US retail prices — $15 per wine bottle, $24 per 24-can beer case, and $30 per spirits bottle — a 100-guest wedding bar costs about $654, or roughly $6.54 per guest. A 200-guest wedding at the same split costs about $1,284, and a 50-guest wedding about $327.
Venue bar packages usually charge far more per person, often $20 to $40 per guest, because they include service, staffing, and glassware. If your venue allows outside alcohol, buying it yourself can save thousands — but you take on the estimating risk.
What drink split should you use for a wedding?
A 40% beer, 40% wine, 20% spirits split suits most weddings and is the default in the calculator. Formal evening weddings with plated dinners lean toward wine; casual or younger crowds drink more beer; cocktail-focused weddings push spirits to 30% or more.
Know your crowd before you lock the split. A family-heavy guest list will drink less overall and want more non-alcoholic options, while a friends-heavy evening wedding will drink more spirits.
Should you add a buffer to your alcohol order?
Yes, a small one. Most planners recommend ordering about 10% more than the calculated amount, or buying from a supplier who accepts returns on unopened bottles. This calculator already rounds every category up to whole bottles and cases, which adds a built-in cushion.
Running out is worse than having leftovers: a dry bar an hour before the end of the night is the detail guests remember.
What about guests who do not drink?
Set the drinker percentage in the calculator to match your guest list — 80% is a typical default, but family-heavy or daytime weddings may be closer to 60 or 70%. Then budget non-alcoholic drinks separately: about one soft drink per non-drinker per hour, plus water, sparkling water, and a mocktail or two.
Non-drinkers are not an afterthought. A thoughtful mocktail menu and good sparkling water cost little and make a real difference to non-drinking guests.
Frequently Asked Questions
How many drinks will 150 guests have at a wedding?
At one drink per guest per hour, 150 guests with 80% drinkers over 4 hours need 480 drinks. At a 40/40/20 split, that is 39 bottles of wine, 8 cases of beer, and 6 bottles of spirits, costing about $957 at the default prices.
Is a beer and wine only bar enough?
Yes. Beer and wine only is a popular, perfectly acceptable bar format that typically cuts alcohol costs by 30 to 40% compared with a full bar. Set spirits to 0% in the calculator and split the rest between beer and wine.
How far in advance should you buy wedding alcohol?
Place your final order two to three weeks before the wedding, once RSVPs are mostly in. That leaves time to adjust if the guest count shifts late.
Does the time of day change how much alcohol you need?
Yes. Evening weddings see higher consumption than afternoon weddings, and longer receptions need proportionally more drinks — that is why reception hours are a direct input in the calculation.
This guide is for planning purposes only. Alcohol quantities are estimates based on the widely used one-drink-per-guest-per-hour rule and standard serving sizes; actual consumption varies with your guests, venue, and event. Always follow local alcohol laws and arrange safe transport for guests.
