Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 75 guests × 75% drinking rate | 56 drinkers |
| Calculate base consumption | 56 drinkers × 1.5 drinks/hour × 5 hours | 420 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.75) | 315 adjusted drinks |
| Apply Labor Day party modifier | × 0.7 (-30% for wine) | 221 wine servings if served alone |
| Share of the bar | 221 servings × 13% | 29 wine servings |
| Convert to bottles | 29 servings ÷ 5 servings per bottle | 5.8 bottles (raw) |
| Add 15% buffer & round up | 5.8 × 1.15 = 6.7, rounded up | 7 bottles |
The Knot's wedding guide plans one drink per guest per hour with a 50/25/25 liquor, beer and wine split. This model counts only the guests who drink, slows the pace after the first hour, and keeps a 15 percent margin; read the methodology.

Wine at a Labor Day party
How much wine do I need for 75 guests?

How much wine per person for a Labor Day party?
Plan for 0.4 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 75 guests, you'll need 7 bottles to provide 29 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 75 guests, roughly 56 will be drinking, and that share works out to 7 bottles.
Should I buy extra wine as a buffer?
Our figure of 7 bottles already includes a 15% buffer (1 extra bottles). That covers guests who drink more than average. It is always better to have leftovers than to run short.
How long will 7 bottles of wine last for 75 guests?
7 bottles of wine will last approximately 5 hours for 75 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.
