context_page_description: A keg is a small barrel.
  Traditionally, a wooden keg is made by a cooper and used to transport items such as nails, gunpowder, and a variety of liquids.
  In recent times, a keg is often constructed of stainless steel. It is commonly used to store, transport, and serve beer. Other alcoholic or non-alcoholic drinks, carbonated or non-carbonated, may be housed in a keg as well. Carbonated drinks are generally kept under pressure in order to maintain carbon dioxide in solution, preventing the beverage from becoming flat.
context_section_description: The mini keg is a 5-liter keg produced for retail sales. Some brands come with a spout and pour from the bottom via gravity, while others may use a low cost pressurized tap. Mini kegs are typically not returned to the manufacturer for cleaning and refilling. The disposable kegs, being made of aluminum, may be recycled.
  In Canada, Molson brewery dubbed the mini keg "Bubba". This name has now been genericized to generally apply to all 5-liter mini kegs in Canada. This might cause confusion, as a company called Bubba Keg is established in the U.S., and appears to not be associated with Molson. Today, mini kegs are widely available in liquor stores worldwide, with Heineken, Grolsch and Bitburger all adopting the design.
  Recently in Austria, beer is available in mini kegs, either by a one-way type keg made of steel or out of a reinforced thermoplastic for about a 4 € deposit.
