Mini Beer Kegs hold around 1.32 gallons of beer.
So that 1.32 gallon mini beer keg holds 14 of the 12 ounce cans of beer or 14 of the 12 ounce bottles of beer.
So if you normally serve say 14 beers from 12 ounce bottles or 12 ounce beer cans then you can get 14 servings of beer out of the mini beer keg.
Or if you're just drinking the beer yourself from a mini beer keg then you should be able to get at least 14 beers out of the mini beer keg.
Those mini beer kegs are cute and make for great decorations as well once you're done drinking the beer from them.
The beer keg mini sizes are usually used in a mini kegerator but you can use them without one as well.
