Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 75 guests × 75% drinking rate | 56 drinkers |
| Calculate base consumption | 56 drinkers × 1.5 drinks/hour × 3 hours | 252 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 2.65) | 223 adjusted drinks |
| Apply wedding shower modifier | × 0.3 (-70% for beer) | 67 beer servings if served alone |
| Share of the bar | 67 servings × 6.8% | 5 beer servings |
| Convert to cases | 5 servings ÷ 24 servings per case | 0.2 cases (raw) |
| Add 15% buffer & round up | 0.2 × 1.15 = 0.2, rounded up | 1 case |
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.

Beer at a wedding shower
How much beer do I need for 75 guests?
You need 1 case of beer for 75 guests at a wedding shower, assuming you are serving a full bar. That is 5 servings with a 15% buffer. If beer is the only alcohol you serve, plan on 4 cases instead.
How much beer per person for a wedding shower?
Plan for 0.1 servings of beer 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 beer is only 6.8 percent of what gets poured.
How many servings are in a case of beer?
One case of beer contains 24 servings. For 75 guests, you'll need 1 case to provide 5 total servings.
What percentage of the bar is beer at a wedding shower?
About 6.8 percent of the drinks poured at a wedding shower are beer. With 75 guests, roughly 56 will be drinking, and that share works out to 1 case.
Should I buy extra beer as a buffer?
Our figure of 1 case already includes a 15% buffer (0 extra case). That covers guests who drink more than average. It is always better to have leftovers than to run short.
How long will 1 case of beer last for 75 guests?
1 case of beer will last approximately 3 hours for 75 guests at a wedding shower, alongside the other drinks on the bar. This factors in the natural slowdown of consumption as the event progresses.
