Kegs, the small barrels that you use to hold, transport, and store carbonated or non-carbonated drinks, is what you are sure to love as a beer aficionado.
Quick Summary: How Many Beers are in a Half Barrel Keg?
The most common keg size for a party (the one that you would get for an event from a local beer store) is the Half Barrel.
At 15.5 gallons (1984 ounces), this equals 165 beers at 12 oz. servings.
A full half-barrel weighs in at 160 pounds! (30lbs empty + 130lbs of liquid). This is why the half barrel is more common than a “Full Barrel,” as the weight is too high to safely transport.
The Half-Barrel is commonly referred to as a full size keg for this reason.
Choosing the right keg before the party is an important step.

Why Do You Need a Keg Anyway?
Carbonated drinks like a beer require pressurized storage, to keep the carbon dioxide in the drinks intact. A Kegerator is a refrigerator specially designed to store these kegs.
Unfortunately, normal refrigerators that you find in homes are not designed to store kegs. You need a kegerator conversion kit to convert your conventional refrigerator into a kegerator.
Knowing what’s the right size of the Keg though can be a confusing topic. There is no official standardized size of kegs. The size of the keg differs from one region to another.
Thankfully, there seem to be some acceptable references in the measurement of kegs. So as you are going to see the sizes of Kegs as per US standards. The number of beers in a keg differs with the size of the Keg (duh).
So when asking the question how many beers are in a keg, you really need to know what keg we are talking about.
There are eight common types of keg, categorized based on shape, size and number of beers it can hold. The Keg, also referred to as a small barrel, is a tiny portion of one barrel. In the United States, a barrel size is equal to 31 gallons. A standard keg is equal to half of the barrel and can hold around 15.5 gallons.
These are categorized into two basic types depending on the components present in assembling the keg. We shall discuss each and every type in detail:
On one side of a keg, there is a gas disconnect. This gas disconnect is then connected to the regulator of a carbon dioxide tank. This carbon dioxide tank regulates the pressure of the drink inside the keg. On the other side of the keg, there is a liquid disconnect.
The liquid disconnect releases beer to the tap handle or picnic tap through the liquid line. There are clamps all over the gas and liquid lines. Also called by it’s full name: Cornelius Keg.
Depending on the lock systems used in gas connect; the corny kegs are categorized into:
- Ball lock kegs
- Pin lock kegs
The Sankey Kegs also have a carbon dioxide tank, gas line, and a liquid line. The only difference between Sankey kegs and Cornelius kegs is the setup of these components.
Unlike Corny kegs, the Sankey kegs have a coupler that combines both gas-in and beer-out line. The coupler acts as an entrance to the gas and releases beer to the tap handle.
In the United States, people use ‘D’ shaped couplers. The major drawback is the difficulty in setting up this keg.
Comparison of Different types of Keg based on the Components:
- Ball Lock Kegs: The ball lock kegs have a ball lock specific gas and liquid disconnects. This keg is slimmer and taller than the pin lock kegs.
- Pin Lock Kegs: The pin lock kegs have a pin-specific lock for gas and liquid disconnects. This keg is shorter and fatter than ball lock kegs. However, you need to replace the pin-lock more often. The older pin lock kegs do not possess manual pressure relief valves.
- Sankey Kegs: It requires coupler to regulate gas and liquid lines. It does not have different gas and liquid disconnects. The coupler is usually in ‘D’ representation in the United States. The setup of these kegs is sophisticated than the Corny Kegs.
Types of Kegs based on Size:
Based on the size and number of beers that a keg can hold, the kegs can be categorized into different types. The standard Keg or a half-barrel can store up to 15.5 gallons of beer.
Let’s discuss each and every type of keg in detail, this will really answer the question “how many beers in a keg?”

The Cornelius Keg differs from other kinds of Kegs in the setup of the components. They do not have different gas and liquid disconnects. Instead, a ‘D’ coupler (commonly used in the United States), is used to regulate the gas and liquid line. The Cornelius keg can hold up to 53 – 12oz beers.
The Cornelius Kegs originally were developed to store soft-drinkers. But the homebrewers now use it to store beers. Since it is easy to clean and maintain, the Cornelius kegs are mostly preferred. You must be familiar with the coupler to regulate the gas and liquid line.
The Cornelius Keg is commonly called as Corny Keg, Soda keg or Homebrew Keg. Because of its easy installation, easy filling up and drawing out, this keg is preferred for home brewing purposes. This keg can also be used to store wine, coffee, and kombucha.
Sixth (1/6) Barrel Keg:
Specifications: Capacity: 5.16 gallons/ 661 ounces. Dimensions: 9-1/4” Dia. X 23-3/8” Height

As the name suggests, the diameter of the slim quarter keg is smaller than the pony keg. This feature makes it look slimmer and taller than the pony keg.
The diameter is similar to that of the sixth barrel keg. The slim feature of this keg makes it more suitable for the dual-tap kegerators. You can store two of these in the kegerator as it occupies little space compared to the pony keg. Though the diameter is similar to the sixth barrel, this keg has a larger width slightly. Therefore, it can store 7.75 gallons, two gallons more than the sixth barrel keg.

There are plenty of ways to keep a keg this size cold without the use of a kegerator also.
Specifications: Capacity: 13.2 gallons/ 1690.7 ounces. Diameter: 16” Dia. X 21” Height
The import keg, also commonly called a European barrel, holds 13.2 gallons of beer. The diameter of the import keg is similar to the full keg. The height and the width specifications of import keg are slightly lesser than the full keg. Since the width is slightly lesser, the import keg can store 2 gallons lesser than the full keg.
The import keg can hold up to 140 beers at 12 oz. servings. Again, these kinds of kegs can be seen only on larger parties or business meetings.
European Half Barrel:
Specifications: Capacity: 6.6 gallons/ 845.4 ounces. Diameter: 16” Dia. X 10.5” Height
The European half barrel, as the name suggests, is a half barrel of the import barrel. This barrel can hold half of the import barrel, that is, 6.6 gallons. This barrel has a diameter similar to the quarter barrel. The width of the European half barrel is slightly smaller than the quarter barrel. Therefore, this barrel can store 1.2 gallons lesser than that of the Quarter barrel.
Since this barrel can store 70 beers at 12 oz, this keg can be used for smaller parties involving 15 to 20 members. This barrel can store varieties of beers, and so is useful for smaller restaurants and bars.

This barrel is the tallest of all the other barrels in this list. The width of this barrel is the smallest when compared to other barrels. Therefore, it looks slimmer and thinner in comparison.
