What size is a half keg?

Answered by Roy Gibson

As an expert sommelier and brewer, I can clarify the size of a half keg for you. A half keg, also known as a half barrel keg, is a popular choice for many enthusiasts. Despite its name, it is important to note that a half keg is not actually half the size of a full keg, which is commonly referred to as a full-sized keg.

A half keg typically holds 15.5 gallons of beer. To give you a better idea of the serving capacity, this translates to approximately 124 pints or 165 twelve-ounce servings. It is a substantial amount of beer, making it a suitable choice for larger gatherings, parties, or events where you expect a decent number of guests.

When I first started my own beer, I remember being a bit confused by the term “half keg.” I initially thought it meant that the keg was physically half the size of a full keg. However, I soon realized that it refers to the volume of beer it can hold rather than its physical dimensions.

To put it into perspective, a half keg is typically taller and wider than a standard 5-gallon keg, which is commonly used by homebrewers. It is larger in size and requires more space for storage and transportation. It is important to consider this factor when planning to purchase or handle a half keg.

When hosting a larger event or party, opting for a half keg can be a practical choice. It eliminates the need for frequent refills and ensures that you have an ample supply of beer to cater to your guests' preferences. However, it is crucial to consider the number of attendees and their beer consumption habits before deciding on the keg size.

In my experience, half kegs are often favored by bars, restaurants, and event organizers who have a high demand for beer. They provide a good balance between quantity and convenience, as they are more manageable compared to full-sized kegs, yet offer a significant serving capacity.

To summarize, a half keg, also known as a half barrel keg, holds 15.5 gallons of beer, equivalent to approximately 124 pints or 165 twelve-ounce servings. Despite the name, it is not physically half the size of a full keg. It is a popular choice for larger gatherings or events where a substantial amount of beer is required. Consider the number of guests and their beer consumption habits when deciding on the appropriate keg size.
