Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 200 guests × 65% drinking rate | 130 drinkers |
| Calculate base consumption | 130 drinkers × 1.5 drinks/hour × 5 hours | 975 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.75) | 731 adjusted drinks |
| Apply wedding modifier | × 1.5 (+50% for champagne) | 1097 champagne servings if served alone |
| Share of the bar | 1097 servings × 16.7% | 183 champagne servings |
| Convert to bottles | 183 servings ÷ 6 servings per bottle | 30.5 bottles (raw) |
| Add 15% buffer & round up | 30.5 × 1.15 = 35.1, rounded up | 36 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 wedding
How much champagne do I need for 200 guests?
You need 36 bottles of champagne for 200 guests at a wedding, assuming you are serving a full bar. That is 183 servings with a 15% buffer. If champagne is the only alcohol you serve, plan on 211 bottles instead.
How much champagne per person for a wedding?
Plan for 0.9 servings of champagne per person at a wedding 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 16.7 percent of what gets poured.
How many servings are in a bottle of champagne?
One bottle of champagne contains 6 servings. For 200 guests, you'll need 36 bottles to provide 183 total servings.
What percentage of the bar is champagne at a wedding?
About 16.7 percent of the drinks poured at a wedding are champagne. With 200 guests, roughly 130 will be drinking, and that share works out to 36 bottles.
Should I buy extra champagne as a buffer?
Our figure of 36 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 36 bottles of champagne last for 200 guests?
36 bottles of champagne will last approximately 5 hours for 200 guests at a wedding, 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 39 bottles. That is one flute for every one of your 200 guests, not just the drinkers, since everyone takes a glass for the toast, at about 6 flutes per bottle with the same 15% buffer.
