If you’re planing a big party or game day extravaganza, you might ask yourself if it’s more economical to buy a beer keg instead of a few cases. Here’s a simple rule of thumb you can use to find out.
Kegs of beer are appealing because they provide a lot of beer for less, you don’t end up with a bunch of cans and bottles lying around, and you don’t have to make room in your fridge for everybody’s six-pack. Still, you probably don’t need one at your Super Bowl party. As Allison Russo at The Kitchn explains, a standard beer keg in the U.S. comes in at about 15.5 gallons, which is roughly equal to 165 12-ounce bottles of beer. That’s about four beers for 41 people, or eight beers for 20. That’s a lot of beer.
Most parties won’t need that much, but if you’re hosting an all-day gathering for a large group of people it could still be worth it—especially if you get a quarter barrel keg instead. But honestly, if you have less than 35 people coming over, you should probably just pick up a few cases. You’ll get more variety anyway.
