Corny kegs, also known as Cornelius kegs, come in a variety of sizes to suit different brewing needs. One common size is the 5 US gallon keg, which is equivalent to 4.16 Imperial gallons or approximately 19 liters. This size is quite popular among homebrewers and small-scale commercial brewers due to its manageable capacity.
The dimensions of a 5-gallon corny keg are typically around 633mm in height and 219mm in diameter. However, it's important to note that these measurements may vary slightly depending on the specific manufacturer and design of the keg. It's always a good idea to check the specifications provided by the manufacturer to ensure that the keg will fit your specific requirements.
When considering the size of a corny keg, it's essential to allow extra space for disconnects and taps, depending on the type of fittings you plan to use. These additional components can increase the overall height and diameter of the keg, so it's crucial to account for them when determining the space needed for storage or dispensing.
In my personal experience as both a sommelier and a brewer, I have found the 5-gallon size to be quite versatile. It is suitable for both small homebrew batches and for serving a moderate number of guests at events or parties. The compact size of the keg makes it easy to handle and store, especially compared to larger keg sizes commonly used in commercial settings.
One advantage of using corny kegs is their compatibility with standard homebrew equipment. Many homebrewers use ball lock or pin lock disconnects, which attach to the keg's posts to provide a secure connection between the keg and the dispensing system. These disconnects can add some height and width to the keg, so it's important to consider their dimensions when planning for storage or fitting the keg into a kegerator or keezer.
It's worth noting that corny kegs are available in other sizes as well, such as 2.5-gallon and 3-gallon kegs. These smaller sizes can be useful for experimental batches or when space is limited. On the other hand, larger corny kegs, such as 10-gallon or 15-gallon options, are also available for those who need to brew or serve larger quantities of beer.
Corny kegs come in various sizes, but the 5 US gallon (19 liters) option is a popular choice among homebrewers and small-scale commercial brewers. The dimensions of a 5-gallon corny keg are typically around 633mm in height and 219mm in diameter, but it's important to consider the additional space needed for disconnects and taps. The compact size and versatility of corny kegs make them a practical option for many brewing applications.
