Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 10 guests × 80% drinking rate | 8 drinkers |
| Calculate base consumption | 8 drinkers × 1.5 drinks/hour × 3 hours | 36 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 2.65) | 32 adjusted drinks |
| Apply wedding shower modifier | × 1.8 (+80% for champagne) | 57 champagne servings if served alone |
| Share of the bar | 57 servings × 50.8% | 29 champagne servings |
| Convert to bottles | 29 servings ÷ 6 servings per bottle | 4.8 bottles (raw) |
| Add 15% buffer & round up | 4.8 × 1.15 = 5.5, rounded up | 6 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 10 guests?
You need 6 bottles of champagne for 10 guests at a wedding shower, assuming you are serving a full bar. That is 29 servings with a 15% buffer. If champagne is the only alcohol you serve, plan on 11 bottles instead.
How much champagne per person for a wedding shower?
Plan for 2.9 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 10 guests, you'll need 6 bottles to provide 29 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 10 guests, roughly 8 will be drinking, and that share works out to 6 bottles.
Should I buy extra champagne as a buffer?
Our figure of 6 bottles already includes a 15% buffer (1 extra bottles). That covers guests who drink more than average. It is always better to have leftovers than to run short.
How long will 6 bottles of champagne last for 10 guests?
6 bottles of champagne will last approximately 3 hours for 10 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 2 bottles. That is one flute for every one of your 10 guests, not just the drinkers, since everyone takes a glass for the toast, at about 6 flutes per bottle with the same 15% buffer.
