How Much Alcohol to Buy for a Wedding: Complete Guide 2026

One of the most Googled wedding questions: How much alcohol do I need? Buy too little and guests go thirsty — buy too much and you're hauling cases home. Here's the definitive guide for 2026.

The Golden Rule of Wedding Alcohol

A good starting formula for a moderate, 5–6 hour reception:

• Wine: 1 bottle per 2 guests (roughly 5 glasses per bottle)
• Beer: 2–3 bottles per guest
• Spirits: 1 bottle per 8–10 guests

For a party of 100 guests that works out to approximately:

• 50 bottles of wine
• 200–300 bottles of beer
• 10–12 bottles of spirits (vodka, whiskey, etc.)

Alcohol by Guest Count: Quick Table

Moderate party, 5–6 hours (wine bottles 750 ml, beer 12 oz, spirits 750 ml):

Count drinking adults only — subtract kids, designated drivers, and non-drinkers before using the table (typically 10–20% of the guest list).

Adjusting by Party Style

Not every crowd is the same. Use these multipliers:

Accounting for Duration

Longer parties need more. Add roughly +15% for every 2 extra hours beyond 6 hours.

Red vs White Wine

A common split for weddings:

• 60% white wine – lighter, crowd-pleasing
• 40% red wine – especially popular in colder months

Also consider having a sparkling wine / prosecco for the toast — plan 1 glass per person.

Cocktail Hour vs. Dinner vs. Dancing

Consumption varies by reception phase:

• Cocktail hour (1 h): ~1 drink per person
• Dinner (2 h): ~1–1.5 drinks per person per hour
• Dancing (3+ h): ~1–2 drinks per person per hour

Total for a 6-hour reception: 6–8 drinks per person on average.

Beer Selection Tips

Offer 2–3 options:

• 1 light lager (crowd pleaser)
• 1 IPA or craft option (for enthusiasts)
• 1 alcohol-free option (increasingly popular)

Non-Alcoholic Beverages

Don't forget:

• Sparkling water: 1 bottle per 3 guests
• Still water: always available
• Soft drinks / juice: 0.3L per guest for mixers
• Coffee and tea: for end of evening

Shopping Strategy

1. Buy from a store that accepts returns – most major retailers accept unopened cases
2. Buy in bulk – warehouse stores offer 15–20% savings
3. Add 15–20% buffer to all estimates
4. Keep receipts – return what you don't use
