What is the volume of a 1/6 barrel of beer?

1. 5.15 gallons

2. 10.5 gallons

3. 15 gallons

4. 3.5 gallons

The correct answer is: 5.15 gallons

The volume of a 1/6 barrel of beer is accurately represented by 5.15 gallons. In the beer industry, a standard barrel (commonly referred to as a full-size keg) is defined as 31 gallons. Therefore, when you divide the 31-gallon barrel by 6, you arrive at approximately 5.16 gallons, which is typically rounded to 5.15 gallons for practical usage. Understanding these standard keg sizes is crucial for anyone involved in beer service, as they impact serving sizes and inventory management. Other available sizes for barrels include the half-barrel and quarter-barrel, which are larger, meaning their volumes do not apply to the specific measurement of a 1/6 barrel.
