For a toast only 3 bottles (one flute per guest at 6 flutes per bottle, with the same buffer)
Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 15 guests × 80% drinking rate | 12 drinkers |
| Calculate base consumption | 12 drinkers × 1.5 drinks/hour × 5 hours | 90 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.75) | 68 adjusted drinks |
| Apply New Year's Eve party modifier | × 2 (+100% for champagne) | 135 champagne servings if served alone |
| Share of the bar | 135 servings × 43.5% | 59 champagne servings |
| Convert to bottles | 59 servings ÷ 6 servings per bottle | 9.8 bottles (raw) |
| Add 15% buffer & round up | 9.8 × 1.15 = 11.3, rounded up | 12 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.

Champagne at a New Year's Eve party
How much champagne do I need for 15 guests?
You need 12 bottles of champagne for 15 guests at a New Year's Eve party, assuming you are serving a full bar. That is 59 servings with a 15% buffer. If champagne is the only alcohol you serve, plan on 26 bottles instead.
How much champagne per person for a New Year's Eve party?
Plan for 3.9 servings of champagne 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 champagne is only 43.5 percent of what gets poured.
How many servings are in a bottle of champagne?
One bottle of champagne contains 6 servings. For 15 guests, you'll need 12 bottles to provide 59 total servings.
What percentage of the bar is champagne at a New Year's Eve party?
About 43.5 percent of the drinks poured at a New Year's Eve party are champagne. With 15 guests, roughly 12 will be drinking, and that share works out to 12 bottles.
Should I buy extra champagne as a buffer?
Our figure of 12 bottles already includes a 15% buffer (2 extra bottles). That covers guests who drink more than average. It is always better to have leftovers than to run short.
How long will 12 bottles of champagne last for 15 guests?
12 bottles of champagne will last approximately 5 hours for 15 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.
How much champagne do I need for just the toast?
For a toast alone, plan on 3 bottles. That is one flute for every one of your 15 guests, not just the drinkers, since everyone takes a glass for the toast, at about 6 flutes per bottle with the same 15% buffer.
