How much wine do I need for 25 guests?

You need 32 bottles of wine for 25 guests at a wedding. This provides 135 total servings with a 15% buffer to ensure you don't run out.

How much wine per person for a wedding?

Plan for 5.4 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 25 guests, you'll need 32 bottles to provide 135 total servings.

What percentage of guests will drink wine at a wedding?

At a wedding with 25 guests, approximately 20 guests (80%) will actively drink. Our formula accounts for this when calculating the 32 bottles you need.

Should I buy extra wine as a buffer?

Yes! Our calculation of 32 bottles already includes a 15% buffer (5 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 32 bottles of wine last for 25 guests?

32 bottles of wine will last approximately 5 hours for 25 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

25 guests × 80% drinking rate

= 20 drinkers

At small events, about 80% of guests typically drink alcohol.

Calculate base consumption

20 drinkers × 1.5 drinks/hour × 5 hours

= 150 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)

= 113 adjusted drinks

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

Apply wedding modifier

× 1.2 (+20% for wine)

= 135 wine servings needed

Weddings typically consume 20% more wine than average.

Convert to bottles

135 servings ÷ 5 servings per bottle

= 27 bottles (raw)

Each bottle of wine provides 5 servings.

Add 15% buffer & round up

27 × 1.15 = 31.0, rounded up

= 32 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.
