Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 300 guests × 65% drinking rate | 195 drinkers |
| Calculate base consumption | 195 drinkers × 1.5 drinks/hour × 5 hours | 1463 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.75) | 1097 adjusted drinks |
| Apply Labor Day party modifier | × 0.7 (-30% for wine) | 768 wine servings if served alone |
| Share of the bar | 768 servings × 13% | 100 wine servings |
| Convert to bottles | 100 servings ÷ 5 servings per bottle | 20 bottles (raw) |
| Add 15% buffer & round up | 20 × 1.15 = 23.0, rounded up | 23 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 300 guests?
You need 23 bottles of wine for 300 guests at a Labor Day party, assuming you are serving a full bar. That is 100 servings with a 15% buffer. If wine is the only alcohol you serve, plan on 177 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 300 guests, you'll need 23 bottles to provide 100 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 300 guests, roughly 195 will be drinking, and that share works out to 23 bottles.
Should I buy extra wine as a buffer?
Our figure of 23 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 23 bottles of wine last for 300 guests?
23 bottles of wine will last approximately 5 hours for 300 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.
