USA Standard Beer Kegs

US kegs come in a variety of sizes

The most common size is the half-barrel keg, which is equal to 15.5 gallons or approximately 124 pints of beer.

Half barrel kegs are also known as "full size" kegs and are the standard size for most draft beer systems.

They are typically made of stainless steel and have a cylindrical shape with a single opening at the top and a valve at the bottom.

The opening at the top is sealed with a removable cap, and the valve at the bottom is used to dispense the beer.

In addition to half-barrel kegs, there are also smaller keg sizes available, such as the quarter barrel keg (7.75 gallons) and the sixth barrel keg (5.16 gallons).

These smaller kegs are often referred to as "slim" or "pony" kegs and are more portable than full-size kegs.

Kegs are commonly used in bars, restaurants, and other establishments that serve draft beer.

They are also popular with home brewers, as they offer a convenient and cost-effective way to store and serve large quantities of beer. In addition, kegs are often used at events like parties and BBQs, as they allow for the easy dispensing of beer to a large number of people.

Overall, kegs are a reliable and convenient option for storing, transporting, and serving draft beer. They come in a variety of sizes to suit different needs, and their standard size and compatibility with various keg-tapping systems make them a popular choice in both commercial and home brewing settings.
