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 × 4 hours | 1170 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.25) | 951 adjusted drinks |
| Apply Thanksgiving modifier | × 0.8 (-20% for beer) | 761 beer servings if served alone |
| Share of the bar | 761 servings × 26.1% | 199 beer servings |
| Convert to cases | 199 servings ÷ 24 servings per case | 8.3 cases (raw) |
| Add 15% buffer & round up | 8.3 × 1.15 = 9.5, rounded up | 10 cases |
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 for a Thanksgiving, by guest count

Full bar figures are beer's share of a four-drink bar for a Thanksgiving, with a 15 percent buffer included.

Beer at a Thanksgiving
How much beer do I need for 300 guests?
You need 10 cases of beer for 300 guests at a Thanksgiving, assuming you are serving a full bar. That is 199 servings with a 15% buffer. If beer is the only alcohol you serve, plan on 37 cases instead.
How much beer per person for a Thanksgiving?
Plan for 0.7 servings of beer per person at a Thanksgiving 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 26.1 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 10 cases to provide 199 total servings.
What percentage of the bar is beer at a Thanksgiving?
About 26.1 percent of the drinks poured at a Thanksgiving are beer. With 300 guests, roughly 195 will be drinking, and that share works out to 10 cases.
Should I buy extra beer as a buffer?
Our figure of 10 cases already includes a 15% buffer (1 extra cases). That covers guests who drink more than average. It is always better to have leftovers than to run short.
How long will 10 cases of beer last for 300 guests?
10 cases of beer will last approximately 4 hours for 300 guests at a Thanksgiving, alongside the other drinks on the bar. This factors in the natural slowdown of consumption as the event progresses.
