Change any assumption you disagree with; the answer follows.

Estimate actual drinkers 250 guests × 65% drinking rate 163 drinkers
Calculate base consumption 163 drinkers × 1.5 drinks/hour × 5 hours 1223 base drinks
Apply consumption decay Adjusted for drinking slowdown over time (decay factor: 3.75) 917 adjusted drinks
Apply Labor Day party modifier × 0.7 (-30% for wine) 640 wine servings if served alone
Share of the bar 640 servings × 13% 83 wine servings
Convert to bottles 83 servings ÷ 5 servings per bottle 16.6 bottles (raw)
Add 15% buffer & round up 16.6 × 1.15 = 19.1, rounded up 20 bottles

Wine at a Labor Day party

How much wine do I need for 250 guests?

You need 20 bottles of wine for 250 guests at a Labor Day party, assuming you are serving a full bar. That is 83 servings with a 15% buffer. If wine is the only alcohol you serve, plan on 148 bottles instead.

How much wine per person for a Labor Day party?

Plan for 0.3 servings of wine per person at a Labor Day party with a full bar. This accounts for the fact that not everyone drinks alcohol, that consumption slows as the event progresses, and that wine is only 13 percent of what gets poured.

How many servings are in a bottle of wine?

One bottle of wine contains 5 servings. For 250 guests, you'll need 20 bottles to provide 83 total servings.

What percentage of the bar is wine at a Labor Day party?

About 13 percent of the drinks poured at a Labor Day party are wine. With 250 guests, roughly 163 will be drinking, and that share works out to 20 bottles.

Should I buy extra wine as a buffer?

Our figure of 20 bottles already includes a 15% buffer (3 extra bottles). That covers guests who drink more than average. It is always better to have leftovers than to run short.

How long will 20 bottles of wine last for 250 guests?

20 bottles of wine will last approximately 5 hours for 250 guests at a Labor Day party, alongside the other drinks on the bar. This factors in the natural slowdown of consumption as the event progresses.
