A 1/4 barrel holds how many gallons of beer?

The correct answer is 7.75 gallons, which is the standard capacity of a 1/4 barrel, also known as a "pony keg." Understanding keg sizes is essential for anyone involved in beer service or brewing, as it helps in proper inventory management and serving of beer. A 1/4 barrel is commonly used for smaller gatherings and is a popular size for bars and restaurants when a full 1/2 barrel is too much.

The other options represent different volumes that do not correspond to the actual capacity of a 1/4 barrel. For example, 5.15 gallons would be too small, while 10 gallons exceeds the capacity of a 1/4 barrel. Similarly, 15.5 gallons corresponds to a 1/2 barrel, which is significantly larger than a 1/4 barrel. Knowing these specifications is crucial for accurately managing beer quantities in various settings.
