If beer is the only alcohol you serve 12 cases (0.8 servings per guest)
Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 300 guests × 65% drinking rate | 195 drinkers |
| Calculate base consumption | 195 drinkers × 1.5 drinks/hour × 3 hours | 878 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 2.65) | 775 adjusted drinks |
| Apply wedding shower modifier | × 0.3 (-70% for beer) | 233 beer servings if served alone |
| Share of the bar | 233 servings × 6.8% | 16 beer servings |
| Convert to cases | 16 servings ÷ 24 servings per case | 0.7 cases (raw) |
| Add 15% buffer & round up | 0.7 × 1.15 = 0.8, 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 300 guests?
You need 1 case of beer for 300 guests at a wedding shower, assuming you are serving a full bar. That is 16 servings with a 15% buffer. If beer is the only alcohol you serve, plan on 12 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 300 guests, you'll need 1 case to provide 16 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 300 guests, roughly 195 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 300 guests?
1 case of beer will last approximately 3 hours for 300 guests at a wedding shower, alongside the other drinks on the bar. This factors in the natural slowdown of consumption as the event progresses.
