How much wine do I need for 15 guests?

You need 18 bottles of wine for 15 guests at a thanksgiving. This provides 76 total servings with a 15% buffer to ensure you don't run out.

How much wine per person for a thanksgiving?

Plan for 5.1 servings of wine per person at a thanksgiving. 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 18 bottles to provide 76 total servings.

What percentage of guests will drink wine at a thanksgiving?

At a thanksgiving with 15 guests, approximately 12 guests (80%) will actively drink. Our formula accounts for this when calculating the 18 bottles you need.

Should I buy extra wine as a buffer?

Yes! Our calculation of 18 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 18 bottles of wine last for 15 guests?

18 bottles of wine will last approximately 4 hours for 15 guests at a thanksgiving. 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 thanksgiving modifier

× 1.3 (+30% for wine)

= 76 wine servings needed

Thanksgivings typically consume 30% more wine than average.

Convert to bottles

76 servings ÷ 5 servings per bottle

= 15.2 bottles (raw)

Each bottle of wine provides 5 servings.

Add 15% buffer & round up

15.2 × 1.15 = 17.5, rounded up

= 18 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 Thanksgiving

Insider advice from experienced bartenders

💡

Wine consumption peaks during dinner - have bottles ready at the table.

⏰

Pre-dinner cocktails should be light so people can enjoy the meal.

🎯

After-dinner drinks (port, brandy) are a nice touch.

🧊

Football watching = beer in the afternoon before dinner.

✨

Designated drivers are essential - plan non-alcoholic options.

🛒 Buying Guide

Thanksgiving is wine-heavy with the meal. Plan 1 bottle of wine per 2 adults at the table. Have a light cocktail option for pre-dinner and maybe some beer for football watching. Keep it classy.
