Knowing beer keg weight and the capacity of each keg is vital for keeping track of the inventory in your bar. This will help you know the number of kegs to order to ensure continued customer service.
This article gives an insight into various keg information, noting each keg’s weight and capacity.
What Is Keg Weight?
Keg weight refers to the different weight and capacity of beer kegs, and a full keg of beer weighs approximately 140 to 160 pounds.
What Are the Different Kinds of Beer Kegs?
The most common kegs used for beers today include the Cornelius, onehalf barrel, onefourth barrel, onesixth barrel, etc. The kegs are often made of stainless steel, sometimes aluminum, coated with plastic on the inside. These two metals are lightweight but are the best materials for handling pressurized and carbonated liquids such as beer.
Keg Weight Chart
A typical halfbarrel filled with beer is 160 pounds. The weight of a keg, either full or empty, depends solely on the different keg sizes and capacity.
The table below shows the different keg types, from the smallest to the biggest, indicating the weight when empty and full, respectively.
Keg Type  Weight (Empty)  Weight (Full) 
Cornelius Keg  9 pounds  55 pounds 
Sixth Keg  15.5 pounds  58 pounds 
Pony Keg  22 pounds  87 pounds 
Quarter Keg  22 pounds  87 pounds 
50 Liter Keg  28 pounds  130 pounds 
Half Barrel  30 pounds  160 pounds 
Now, let’s take a more detailed approach into these kegs, describing their features and providing other necessary information.
– What Is the Weight of a Cornelius Keg?
Cornelius kegs, commonly called corny kegs, weigh 9 pounds when empty and 55 pounds when filled with beer. Corny kegs are stainless steel canisters that formerly hold soda drinks in industries. They are the goto options for kegging homebrews and other pressurized beverages like soda and sparkling water.
Most craft breweries use these kegs because they are cheap and easy to fill and clean. At the top of corny kegs is a large opening for filling fresh brew. These kegs have two forms of fitting setups: the pin lock and the ball lock. Either configuration has different kinds of connectors with an airtight seal.
– How Heavy Is a Sixth Barrel?
A sixth barrel keg weighs 15.5 pounds when empty and 58 pounds when filled. The sixth, or sixtel, is sometimes called the torpedo because of its similar figure. It is identical to the Cornelius in weight and capacity, though the sixth is larger and considered the industry standard.
The sixtel is probably the most popular option to keg beer in craft brewing. It is ideal for home brewing because of its small profile. Also, it is easy to transport and store in a kegerator. Most restaurants and bars like the size of this keg as they help to manage space. They get to have multiple taps serving variety to satisfy customers better.
– How Much Does a Pony Keg Weigh?
The pony weighs 22 pounds when empty and 87 pounds when filled. Ponies are a short, stubby version of a typical quarter keg. They have similar weights, albeit different dimensions. The keg design makes it easy to move around; you’ll often find these kegs at backyard gatherings or parties.
The kegs are not as common as quarter and half barrels as they are too short, making working with them quite inconvenient. For instance, when you put a pony in a keezer or kegerator, they soon take up all the space that would probably contain two to three slimmer kegs like the sixth, Cornelius or even a slim quarter keg.
– How Heavy Is a Quarter Keg?
The quarter keg has the same weight and capacity as the pony, so a full quarter keg weighs 87 pounds; however, it weighs 22 pounds when empty. Unlike the pony barrel, it is slim and, as a result, sometimes called a “slim” quarter keg. The keg is half the size of a half barrel, though that is a large capacity since a half barrel is a tank.
When planning a gathering amongst friends, this is an ideal size. They are more convenient to work with than half barrels. For instance, having two or more slim quarter kegs in an event, rather than a single half barrel, would create multiple outlets for collecting beer, thereby reducing the length of the queue. Also, it will allow you to serve more than one type of beer.
– How Much Does a Half Keg Weigh?
An empty halfbarrel keg weighs 30 pounds and 160 pounds when full. Half Barrels are more or less a tank as they are very heavy, especially when filled. These vessels are perhaps the most common for storing beer. Half barrels are the typical barrel you’d find in bars, restaurants, parties and events in various hospitality industries.
These kegs are sometimes called the fullsize keg as they are the largest available to most craft breweries. Taprooms and bars find these kegs costeffective, as they can contain a large volume of brews for serving various customers. Instead of buying numerous smaller kegs, for example, a single halfbarrel has more capacity than three corny kegs.
– What Is 50L Keg Weight?
The 50liter keg weighs 28 pounds when empty and 130 pounds when filled. It is quite similar to the half barrel in size, but it is a little smaller. That is, the kegs, when full, contain 102 pounds of beer.
The 50liter keg is uncommon in the US.
However, it is the most common keg type in Europe.
Often, when you import beer (kegs) from Europe, they do come in a 50liter keg. It is the goto kegging option over there.
– Mini Keg
The mini is another keg variant that is best suited for miniature kegerators. They are often for a onetime event, as they are primarily used as disposable kegs. Also, they are often for individual beers. Henieken and Coors lager are examples of beers that use this keg.
The disadvantage of this keg is the difficulty of finding one with the specific beer you want. However, they are a good option for spending time with a couple of friends on a small gettogether or a camping trip.
How Many Servings of Beer Are in a Keg?
Like the question on the weight of kegs, keg sizing also isn’t a direct answer question as Keg size information depends on the individual kegs. For example, a corny beer can hold five gallons of beer, whereas that of a half barrel would be at least three times that. Let’s examine the amount of beer each keg can hold.
– How Much Beer in My Corny Keg?
As earlier stated, a corny keg can hold 5 gallons of beer. To better put that into perspective, let’s answer the question: how many beers are in a corny keg? Most beer cans and bottles come in either 12 or 16 ounces.
That said, a corny keg can hold 40 16ounce cans or 53 12ounce bottles of beer. The keg’s dimension is 23 inches by 9 inches, which further suggests that it’s a slim keg that easily fits into a kegerator.
– How Much Beer Can a Sixthbarrel Keg Hold?
This keg is just a little bigger than the Cornelius, so it can hold 5.16 gallons of beer. Likewise, the number of 12ounce and 16ounce beers it can contain are quite similar to those of the corny. A sixth keg would hold 41 16ounce pints and 55 12ounce bottles or cans.
The keg’s dimensions are similar, though the sixth keg is a little bigger. It measures 23.375 inches by 9.250 inches.
– How Much Beer Is in a Pony?
Pony barrels are larger than corny kegs, with a holding capacity of about 7.75 gallons. Using the 12 and 16 ounces beer bottle or can illustration, a pony can hold up to 62 16 ounces pints of beer or 82 12ounces bottles of beer. The keg’s dimensions are 13.875 inches by 16.125 inches.
Remember, we earlier said the pony keg and quarter kegs are similar, with the only difference being that the quarter keg is slim while the pony is short and stubby. Hence, even though they have the same capacity, the dimensions, of course, are different. That said, a quarter keg measures 23.375 inches by 11.175 inches.
– How Much Beer Can a Half Barrel Hold?
Half barrel’s capacity triples that of a sixth and doubles a quarter, which means it can hold beer of up to 15.5 gallons. A half keg is more or less a combination of three sixth kegs or twoquarter kegs.
The full keg will contain 165 12ounce bottles or cans or 124 16oz pints of beer. This tells you the large capacity of this tank. The three (sixth, quarter and half barrels) have the same height, 23.375 inches. The capacity of a half keg weight is a measure of its increased width at 16.175 inches.
– How Many Beers Are in a 50 Liter Keg?
The 50liter keg has a holding capacity of about 13.2 gallons. That is approximately 105 16ounce pints or 140 12ounce cans or bottles. 50liter kegs have dimensions quite similar to half barrels; 20.94 inches by 16.06 inches.
– How Much Beer Is in a Mini Keg?
The miniature keg has a capacity of barely 1.32 gallons. They are pretty small. The beer content is even less than onetenth that of a fullsized keg (half a barrel). The dimensions of this disposable keg are usually around 9.875 inches by 6.75 inches.
How To Weigh Kegs for Bar Inventory?
Beer kegs are usually weighed with the aid of a keg scale. Taking the weights of kegs of beer is the most precise method of taking the inventory of kegs in a bar.
To count kegs in stock using a scale, below are five steps to follow.

Take Weight of Keg When Full
This step is straightforward. Weigh the full keg using your scale and record the weight. The knowledge of such a keg’s full weight would help make comparisons with its weight when partially filled.

Take Weight of Keg When Empty
The weight of a keg containing beer or any other liquid is the combined weight of the keg and its beer. To know the exact keg weight, you will need to weigh an empty keg. That way, even when the keg is full or partially filled, you can account for the weight of its content.
A simple subtraction of the empty keg’s weight from the total weight when filled with beer, would give the weight of the beer it contains. For instance, you weigh an empty keg to be 25 pounds. After filling with beer, it weighs 100 pounds. From this, we can infer that the weight of beer in the keg is 75 pounds.
The knowledge of the empty keg weight helps prevent overestimating the weight of the beer. Recording the weight of a keg containing beer as the weight of beer is wrong. Hence, the need to always have the weight of empty kegs on record.

Take Keg Weight During Inventory
With the aid of your keg scale, weigh and record the readings of all the kegs in the bar. Weigh the empty kegs, partially filled ones, and the fully filled ones. After all, all the kegs, either full, empty, or partially filled, are all part of the inventory. You need to have a record of all the kegs in your bar.

Calculate the Volume Remaining in Each Keg
The calculation of the volume remaining in the keg is often done in the form of percentages. The formula is quite straightforward. You divide the weight of beer remaining in the keg by the weight of the beer the keg can contain.
To express this in mathematical terms, we’d have:
Percentage of beer remaining = (Weight of Partially full keg – Weight of empty keg) / ( Weight of full keg – Weight of empty keg).
Using our illustration, say the weight of the filled keg is 125 pounds. That means the weight of beer the keg contains when full is: (125 – 25), which will result in 100 pounds. Therefore, the percentage of beer remaining in the keg will be 75 ÷ 100, which is equal to 75 percent. This means that our keg is 75 percent filled.

Record Total Inventory
Now you have all the records obtained for the amount of each product available in your bar. The next thing is to log in all the inventories to a more sophisticated record system. You can do this on a spreadsheet or whatever software you use for your bar.
It is always essential to keep records of the inventory in the bar from time to time.
Conclusion
This article gave you detailed information on keg and beer weight and other size information. With that being said, let’s summarize all that the article entails.
 There are six common keg types used for beers, with the largest and heaviest being the Half barrel. The smallest keg is the mini, but going by the industry standard, the sixth is the smallest.
 The article provides information on the number of 12ounces bottles or cans of beer each keg can contain. Also, we gave the overall capacity of each keg in gallons.
 Whenever you want to weigh kegs for your inventory, you should first take the weight of the kegs when they are empty. Then take the weight when full before calculating the volume remaining in the keg.
If you need information on the weight and sizes of the different kegs for storing beer, then this article is just what you need.
