Different keg sizes serve varying purposes and can be used in different situations.
But if you don’t know what to use for the purpose you have in mind, you better know the sizes and capacities of each keg.
So, here we detail how many ounces are in a keg to help you identify the right barrel according to your needs.
How Many Ounces Are In A Keg?
The number of ounces in a keg varies depending on its size. There are seven different keg sizes, and each keg can hold a specific volume of beer.
The Mini keg, the smallest in size, can hold up to 169 oz of beer, while the Half-Barrel keg, the largest in size, can hold up to 1,984 oz of beer.
How Many Ounces Are In Different Keg Sizes?
Sixth Barrel Keg
Ounces: 661 oz = 41 (16oz) glasses or 55 (12oz) cans/bottles
The Sixth Barrel Keg is commonly used in dual or triple-tap setups. Like the Cornelius Keg, this smaller one functions like its bigger cousins. It only holds less beer than other similar-sized containers.
This size can be used for bars and restaurants with limited space but still want a large selection of beer available to their customers.
50 Litre Keg
Ounces: 1690 oz = 105 (16oz) glasses or 140 (120z) cans/bottles
The 50 Liter Keg is commonly used by European breweries and is similar to the Half Barrel in size. This type of container is most commonly found in the UK and other European countries.
Some of the popular imports from the US include Stella Artois, Newcastle, Hoegaarden, and Heineken.
But you should know that import kegs do not utilize a standard Sankey D-type coupling.
Slim Quarter Keg
Ounces: 992 oz = 62 (16oz) glasses or 82 (12oz) cans/bottles
The Slim Quarter Keg is similar to the Quarter barrel in size. So, this makes it a popular choice among dual-tapers.
“A bottle of beer contains more philosophy than all the books in the world.”
— Louis Pasteur, French Chemist
Besides, Slim Quarter Kegs are tall and skinny versions of the Sixth Barrel. Its slightly larger width allows it to hold an additional two gallons of beer.
Cornelius Keg
Ounces: 640 oz = 40 (16oz) glasses or 53 (12oz) cans/bottles
Originally developed for the soft drink industry, people who make beer or soda at home often use these. Cornelius Keg is easy to clean and fill up.
It comes in two types of connectors: pin-lock and ball-lock.
Half Barrel Keg
Ounces: 1984 oz = 124 (16oz) glasses or 165 (12oz) cans/bottles
This Half Barrel Keg is the most common type of beer container people think of when picturing a beer keg.
Actually, it’s a vessel that’s been used to distribute macro-brews for many years.
Also, this is a standard-sized beer keg that most establishments use. It fits most standard-sized containers.
So if you plan on trying new recipes, you might want to use the smaller sizes.
Mini Keg
Ounces: 169 oz = 10 (16oz) glasses or 14 (12oz) cans/bottles
The Mini Keg is ideal for portable or one-time use. It can be used for a variety of activities, such as watching the game with friends or hosting a small dinner party.
Unfortunately, finding a specific beer is not always easy with these.
Quarter Barrel Keg
Ounces: 992 oz = 62 (16oz) glasses or 82 (12oz) cans/bottles
The Quarter Barrel is a stubby and shorter keg. Compared to a Full Barrel, it measures 16 1/8 inches wide and about 10 inches shorter in height.
Alternative names for Quarter Barrel Keg are Pony Keg, Stubby Quarter, or 1/4 BBL.
