How much wine do I need for 10 guests?

You need 9 bottles of wine for 10 guests at a halloween party. This provides 35 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 10 guests, you'll need 9 bottles to provide 35 total servings.

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

At a halloween party with 10 guests, approximately 8 guests (80%) will actively drink. Our formula accounts for this when calculating the 9 bottles you need.

Should I buy extra wine as a buffer?

Yes! Our calculation of 9 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 9 bottles of wine last for 10 guests?

9 bottles of wine will last approximately 4 hours for 10 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

10 guests × 80% drinking rate

= 8 drinkers

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

Calculate base consumption

8 drinkers × 1.5 drinks/hour × 4 hours

= 48 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)

= 39 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)

= 35 wine servings needed

Halloween Partys typically consume 10% less wine than average.

Convert to bottles

35 servings ÷ 5 servings per bottle

= 7 bottles (raw)

Each bottle of wine provides 5 servings.

Add 15% buffer & round up

7 × 1.15 = 8.0, rounded up

= 9 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.

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.
