How Much Champagne for a 250-Guest Wedding Shower?

Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 250 guests × 65% drinking rate | 163 drinkers |
| Calculate base consumption | 163 drinkers × 1.5 drinks/hour × 3 hours | 734 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 2.65) | 648 adjusted drinks |
| Apply wedding shower modifier | × 1.8 (+80% for champagne) | 1163 champagne servings if served alone |
| Share of the bar | 1163 servings × 50.8% | 591 champagne servings |
| Convert to bottles | 591 servings ÷ 6 servings per bottle | 98.5 bottles (raw) |
| Add 15% buffer & round up | 98.5 × 1.15 = 113.3, rounded up | 114 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 shower
How much champagne do I need for 250 guests?
You need 114 bottles of champagne for 250 guests at a wedding shower, assuming you are serving a full bar. That is 591 servings with a 15% buffer. If champagne is the only alcohol you serve, plan on 223 bottles instead.
How much champagne per person for a wedding shower?
Plan for 2.4 servings of champagne per person at a wedding shower 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 50.8 percent of what gets poured.
How many servings are in a bottle of champagne?
One bottle of champagne contains 6 servings. For 250 guests, you'll need 114 bottles to provide 591 total servings.
What percentage of the bar is champagne at a wedding shower?
About 50.8 percent of the drinks poured at a wedding shower are champagne. With 250 guests, roughly 163 will be drinking, and that share works out to 114 bottles.
Should I buy extra champagne as a buffer?
Our figure of 114 bottles already includes a 15% buffer (15 extra bottles). That covers guests who drink more than average. It is always better to have leftovers than to run short.
How long will 114 bottles of champagne last for 250 guests?
114 bottles of champagne will last approximately 3 hours for 250 guests at a wedding shower, 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 48 bottles. That is one flute for every one of your 250 guests, not just the drinkers, since everyone takes a glass for the toast, at about 6 flutes per bottle with the same 15% buffer.
