How much wine do I need for 150 guests?

You need 148 bottles of wine for 150 guests at a holiday party. This provides 640 total servings with a 15% buffer to ensure you don't run out.

How much wine per person for a holiday party?

Plan for 4.3 servings of wine per person at a holiday party. 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 150 guests, you'll need 148 bottles to provide 640 total servings.

What percentage of guests will drink wine at a holiday party?

At a holiday party with 150 guests, approximately 105 guests (70%) will actively drink. Our formula accounts for this when calculating the 148 bottles you need.

Should I buy extra wine as a buffer?

Yes! Our calculation of 148 bottles already includes a 15% buffer (20 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 148 bottles of wine last for 150 guests?

148 bottles of wine will last approximately 4 hours for 150 guests at a holiday party. 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

150 guests × 70% drinking rate

= 105 drinkers

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

Calculate base consumption

105 drinkers × 1.5 drinks/hour × 4 hours

= 630 base drinks

Industry standard is 1.5 drinks per person per hour for a 4-hour event.

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 3.25)

= 512 adjusted drinks

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

Apply holiday party modifier

× 1.25 (+25% for wine)

= 640 wine servings needed

Holiday Partys typically consume 25% more wine than average.

Convert to bottles

640 servings ÷ 5 servings per bottle

= 128 bottles (raw)

Each bottle of wine provides 5 servings.

Add 15% buffer & round up

128 × 1.15 = 147.2, rounded up

= 148 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.

🛒 Buying Guide

Holiday parties call for festive options. Stock extra red wine and have ingredients for 1-2 seasonal cocktails (mulled wine, spiked cider, or classic eggnog). For NYE specifically, double your champagne order and have everything chilled by 11pm.
