How much wine do I need for 100 guests?

You need 109 bottles of wine for 100 guests at a wedding. This provides 473 total servings with a 15% buffer to ensure you don't run out.

How much wine per person for a wedding?

Plan for 4.7 servings of wine per person at a wedding. This accounts for the fact that not everyone drinks alcohol and consumption naturally slows as the event progresses.

How many servings are in a bottle of wine?

One bottle of wine contains 5 servings. For 100 guests, you'll need 109 bottles to provide 473 total servings.

What percentage of guests will drink wine at a wedding?

At a wedding with 100 guests, approximately 70 guests (70%) will actively drink. Our formula accounts for this when calculating the 109 bottles you need.

Should I buy extra wine as a buffer?

Yes! Our calculation of 109 bottles already includes a 15% buffer (14 extra bottles). This ensures you won't run out even if some guests drink more than average. It's always better to have leftovers than to run short.

How long will 109 bottles of wine last for 100 guests?

109 bottles of wine will last approximately 5 hours for 100 guests at a wedding. This calculation factors in the natural slowdown of consumption as the event progresses.

How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

100 guests × 70% drinking rate

= 70 drinkers

At large events, about 70% of guests typically drink alcohol.

Calculate base consumption

70 drinkers × 1.5 drinks/hour × 5 hours

= 525 base drinks

Industry standard is 1.5 drinks per person per hour for a 5-hour event.

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 3.75)

= 394 adjusted drinks

People drink faster in the first hour and slow down as the event progresses.

Apply wedding modifier

× 1.2 (+20% for wine)

= 473 wine servings needed

Weddings typically consume 20% more wine than average.

Convert to bottles

473 servings ÷ 5 servings per bottle

= 94.6 bottles (raw)

Each bottle of wine provides 5 servings.

Add 15% buffer & round up

94.6 × 1.15 = 108.8, rounded up

= 109 bottles

Always round up and add a buffer. Running out is worse than having leftovers!

* Why trust this formula?

Based on industry standards and refined by bartenders with 30+ years of experience. We factor in consumption decay (people drink less as events progress) and real-world drinking percentages.

Pro Tips for Your Wedding

Insider advice from experienced bartenders

💡

40% of all alcohol is consumed during cocktail hour - front-load your bar staff and ice.

⏰

Offer 1-2 signature cocktails instead of a full bar to cut spirit costs by 40% and speed up service.

🎯

Pre-pour wine at dinner tables 5 minutes before guests sit to prevent service bottlenecks.

🧊

Order 10-15% extra and ask vendors about their return policy on unopened bottles.

✨

If dancing goes past 10pm, reopen a simplified bar: beer, wine, and 2 signature drinks only.

🛒 Buying Guide

For weddings, plan a 60/40 split between red and white wine for fall/winter, or flip it for spring/summer. Budget $12-18 per bottle for a crowd-pleasing selection - guests can't tell the difference between $15 and $40 wine at a party. Consider having champagne for toasts separate from your open bar calculation.
