An interesting fact about kegs is that they used to be made from wood. Before modern technology allowed for metal kegs, they were made of wood, usually oak, and were very sturdy and lightweight. The most popular keg sizes were 20-30 gallons and many would line up along taverns for easy access for customers. This practice dates back to the Middle Ages and is still seen in some traditional pubs today. With the invention of metal kegs, the wooden keg has gone by the wayside, but it remains an interesting fact about the history of kegs. Source:
