Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 100 guests × 70% drinking rate | 70 drinkers |
| Calculate base consumption | 70 drinkers × 1.5 drinks/hour × 4 hours | 420 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.25) | 341 adjusted drinks |
| Apply holiday party modifier | × 1.25 (+25% for wine) | 427 wine servings if served alone |
| Share of the bar | 427 servings × 34.8% | 149 wine servings |
| Convert to bottles | 149 servings ÷ 5 servings per bottle | 29.8 bottles (raw) |
| Add 15% buffer & round up | 29.8 × 1.15 = 34.3, rounded up | 35 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 holiday party
How much wine do I need for 100 guests?
You need 35 bottles of wine for 100 guests at a holiday party, assuming you are serving a full bar. That is 149 servings with a 15% buffer. If wine is the only alcohol you serve, plan on 99 bottles instead.
How much wine per person for a holiday party?
Plan for 1.5 servings of wine per person at a holiday 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 34.8 percent of what gets poured.
How many servings are in a bottle of wine?
One bottle of wine contains 5 servings. For 100 guests, you'll need 35 bottles to provide 149 total servings.
What percentage of the bar is wine at a holiday party?
About 34.8 percent of the drinks poured at a holiday party are wine. With 100 guests, roughly 70 will be drinking, and that share works out to 35 bottles.
Should I buy extra wine as a buffer?
Our figure of 35 bottles already includes a 15% buffer (5 extra bottles). That covers guests who drink more than average. It is always better to have leftovers than to run short.
How long will 35 bottles of wine last for 100 guests?
35 bottles of wine will last approximately 4 hours for 100 guests at a holiday party, alongside the other drinks on the bar. This factors in the natural slowdown of consumption as the event progresses.
