How Many Beers Are in a Log?


In the world of beer, various measurements and terminologies are used to describe quantities and volumes. One such term is a "beer log." A beer log refers to a specific quantity of beer contained in a single vessel or container. Understanding the concept of a beer log and the number of beers it typically holds is essential for both brewers and beer enthusiasts. This article aims to provide an overview of beer logs, their historical significance, and the approximate number of beers found in a log.

In-Depth Review and Comparisons

What is a Beer Log?

A beer log, also known as a keg, is a cylindrical container used to store and dispense beer. It is commonly made of stainless steel or aluminum and comes in various sizes, ranging from small party kegs to large commercial kegs. The term "log" is derived from the historical practice of storing beer in wooden barrels, which resembled logs in shape.

Beer Log Sizes and Capacities

Beer logs come in different sizes, each with its own capacity. The most common beer log sizes include:

  1. Half Barrel (Full Size): This is the standard commercial beer log size, also known as a full-size keg. It typically holds approximately 15.5 gallons or 165 12-ounce beers.

  2. Quarter Barrel: Also known as a pony keg, a quarter barrel holds approximately 7.75 gallons or 82 12-ounce beers.

  3. Sixth Barrel: Commonly referred to as a sixtel, this smaller beer log size holds approximately 5.16 gallons or 55 12-ounce beers.

  4. Cornelius Keg: Often used by homebrewers, a Cornelius keg holds approximately 5 gallons or 53 12-ounce beers.

Historical Significance of Beer Logs

The use of beer logs dates back centuries and has played a significant role in the brewing industry. In ancient times, beer was stored and transported in wooden barrels, which were often referred to as logs. These barrels were essential for preserving the beer's quality and allowing for easy distribution. Over time, the materials and sizes of beer logs have evolved, but the concept remains the same.

Calculating the Number of Beers in a Log

To determine the number of beers in a beer log, it is crucial to consider the log's size and the standard serving size of beer, which is typically 12 ounces. By dividing the log's capacity by 12, we can estimate the approximate number of beers it can hold. However, it's important to note that some beer logs may have slightly different capacities due to variations in manufacturing and design.


Beer logs, or kegs, are an integral part of the brewing industry and beer culture. Understanding the sizes and capacities of beer logs allows brewers and consumers to plan accordingly for events, parties, and gatherings. Whether it's a full-size keg for a large celebration or a smaller keg for a more intimate gathering, beer logs provide convenience and a communal experience for beer enthusiasts worldwide.
