How much can a corny keg hold?

Answered by Charles Pate

As an experienced sommelier and brewer, I have had the pleasure of working with corny kegs extensively. These kegs, also known as Cornelius kegs, are popular among home brewers and enthusiasts due to their convenient size and versatility. In this detailed answer, I will provide you with a comprehensive overview of the different sizes of corny kegs available and their respective capacities.

1. 2.378 Gallon Corny Keg:
– This is the smallest size available and is commonly referred to as the “corny pony keg.”
– It holds approximately 9 liters or 2.5 gallons of liquid.
– The compact size makes it perfect for small batches or experimental brews.
– It is also a popular choice for those who want to have a variety of beers on tap without committing to larger quantities.

2. 3 Gallon Corny Keg:
– Slightly larger than the corny pony keg, this size can hold around 11 liters or 3 gallons of liquid.
– It provides a bit more capacity, allowing for a slightly larger batch of beer or other carbonated beverages.
– This size is often preferred by homebrewers who like to experiment with different recipes or flavors in smaller quantities.

3. 5 Gallon Corny Keg:
– The 5-gallon corny keg is undoubtedly the most popular size among homebrewers and beer enthusiasts.
– It can hold approximately 19 liters or 5 gallons of liquid, making it ideal for standard-sized batches.
– This size is commonly used for kegerators, home bars, or gatherings where a larger quantity of beer is desired.
– It offers a good balance between quantity and ease of handling.

4. 10 Gallon Corny Keg:
– The largest size available, the 10-gallon corny keg, is primarily used in commercial settings or by avid homebrewers.
– It can hold around 38 liters or 10 gallons of liquid, allowing for substantial batch sizes.
– This size is typically used for events, parties, or by those who brew beer in larger quantities.
– Handling and storing a 10-gallon keg can be more challenging due to its size and weight.

When selecting a corny keg size, it is essential to consider your goals, available storage space, and intended usage. While the 5-gallon corny keg is the most common and versatile option, the other sizes offer flexibility for different brewing scenarios.

Personally, I have found the 5-gallon corny keg to be perfect for my home brewing needs. It provides enough beer to share with friends and family, fits well in my kegerator, and allows me to experiment with different beer styles without committing to a large quantity. However, I have also used the smaller 2.378-gallon corny kegs for experimental brews or when I want to have multiple beers on tap simultaneously.

Corny kegs come in various sizes, ranging from 2.378 gallons to 10 gallons. The most common size among homebrewers is the 5-gallon keg, offering a balanced capacity for standard-sized batches. Consider your brewing goals and available space when selecting the appropriate corny keg size for your needs. Cheers!
