Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 150 guests × 70% drinking rate | 105 drinkers |
| Calculate base consumption | 105 drinkers × 1.5 drinks/hour × 5 hours | 788 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.75) | 591 adjusted drinks |
| Apply New Year's Eve party modifier | × 1.1 (+10% for wine) | 650 wine servings if served alone |
| Share of the bar | 650 servings × 21.7% | 141 wine servings |
| Convert to bottles | 141 servings ÷ 5 servings per bottle | 28.2 bottles (raw) |
| Add 15% buffer & round up | 28.2 × 1.15 = 32.4, rounded up | 33 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 New Year's Eve party
How much wine do I need for 150 guests?
You need 33 bottles of wine for 150 guests at a New Year's Eve party, assuming you are serving a full bar. That is 141 servings with a 15% buffer. If wine is the only alcohol you serve, plan on 150 bottles instead.
How much wine per person for a New Year's Eve party?
Plan for 0.9 servings of wine per person at a New Year's Eve 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 21.7 percent of what gets poured.
How many servings are in a bottle of wine?
One bottle of wine contains 5 servings. For 150 guests, you'll need 33 bottles to provide 141 total servings.
What percentage of the bar is wine at a New Year's Eve party?
About 21.7 percent of the drinks poured at a New Year's Eve party are wine. With 150 guests, roughly 105 will be drinking, and that share works out to 33 bottles.
Should I buy extra wine as a buffer?
Our figure of 33 bottles already includes a 15% buffer (4 extra bottles). That covers guests who drink more than average. It is always better to have leftovers than to run short.
How long will 33 bottles of wine last for 150 guests?
33 bottles of wine will last approximately 5 hours for 150 guests at a New Year's Eve party, alongside the other drinks on the bar. This factors in the natural slowdown of consumption as the event progresses.
