How much wine do I need for 15 guests?

You need 13 bottles of wine for 15 guests at a halloween party. This provides 53 total servings with a 15% buffer to ensure you don't run out.

How much wine per person for a halloween party?

Plan for 3.5 servings of wine per person at a halloween 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 15 guests, you'll need 13 bottles to provide 53 total servings.

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

At a halloween party with 15 guests, approximately 12 guests (80%) will actively drink. Our formula accounts for this when calculating the 13 bottles you need.

Should I buy extra wine as a buffer?

Yes! Our calculation of 13 bottles already includes a 15% buffer (2 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 13 bottles of wine last for 15 guests?

13 bottles of wine will last approximately 4 hours for 15 guests at a halloween 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

15 guests × 80% drinking rate

= 12 drinkers

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

Calculate base consumption

12 drinkers × 1.5 drinks/hour × 4 hours

= 72 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)

= 59 adjusted drinks

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

Apply halloween party modifier

× 0.9 (-10% for wine)

= 53 wine servings needed

Halloween Partys typically consume 10% less wine than average.

Convert to bottles

53 servings ÷ 5 servings per bottle

= 10.6 bottles (raw)

Each bottle of wine provides 5 servings.

Add 15% buffer & round up

10.6 × 1.15 = 12.2, rounded up

= 13 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 Halloween Party

Insider advice from experienced bartenders

💡

Specialty cocktails with spooky names are a must - batch them ahead.

⏰

Dark spirits (whiskey, dark rum) fit the theme better than clear spirits.

🎯

Punch bowls with dry ice create amazing effects.

🧊

People in elaborate costumes drink slower - they don't want to spill.

✨

Adult-only parties consume 40% more than family Halloween events.

🛒 Buying Guide

Halloween parties are cocktail-heavy. Plan for 2-3 specialty cocktails per person plus regular bar options. Red wine fits the theme well. Have themed cups and garnishes.
