How Many Beers Are in a Keg?

When people first started using the word keg back in the 17th century, according to the Oxford English Dictionary, it described “a small barrel or cask, usually of less than 10 gallons.”

It didn’t come to mean a barrel of beer, specifically, until the mid-20th century. Though you can order kegs of other beverages—wine, soda, etc.—these days, it’s pretty safe to assume that if someone mentions getting a keg for their upcoming party, there’s going to be beer in it. What’s slightly less safe to assume is just how many red solo cups it will fill. And that’s because kegs aren’t all the same size.

But they are more or less standardized across keg providers, who are typically good about breaking down the dimensions and capacity of each kind on their websites. Read on for details from KegWorks and Buy Keg Beer.

Just a tad larger than a corny keg, the sixth-barrel is ideal for smaller establishments who prioritize variety over quantity.

Slim-quarter kegs hold the same amount of beer as a regular quarter-barrel, but dual- and triple-tap kegerators can better accommodate their shape.

This is the kind of keg you usually see at big parties—hence why it’s considered a “full” or “full-size” keg.

The 50-litre keg, popular in Europe, requires a different kind of keg coupler.
