Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 25 guests × 80% drinking rate | 20 drinkers |
| Calculate base consumption | 20 drinkers × 1.5 drinks/hour × 3 hours | 90 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 2.65) | 80 adjusted drinks |
| Apply wedding shower modifier | × 1.8 (+80% for champagne) | 143 champagne servings if served alone |
| Share of the bar | 143 servings × 50.8% | 73 champagne servings |
| Convert to bottles | 73 servings ÷ 6 servings per bottle | 12.2 bottles (raw) |
| Add 15% buffer & round up | 12.2 × 1.15 = 14.0, rounded up | 14 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 25 guests?
You need 14 bottles of champagne for 25 guests at a wedding shower, assuming you are serving a full bar. That is 73 servings with a 15% buffer. If champagne is the only alcohol you serve, plan on 28 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 25 guests, you'll need 14 bottles to provide 73 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 25 guests, roughly 20 will be drinking, and that share works out to 14 bottles.
Should I buy extra champagne as a buffer?
Our figure of 14 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 14 bottles of champagne last for 25 guests?
14 bottles of champagne will last approximately 3 hours for 25 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 5 bottles. That is one flute for every one of your 25 guests, not just the drinkers, since everyone takes a glass for the toast, at about 6 flutes per bottle with the same 15% buffer.
