too large to fit in a typical home refrigerator. A kegerator (specially designed for kegs, or converted from a suitable small refrigerator) can be used, but as these are somewhat specialized they are cost-prohibitive for the average consumer who has only occasional use for one, and are obviously impractical to bring to a beach or campsite. Instead, in the US and Australia, kegs are usually kept in a bucket of ice and/or water to keep the beer cool. Alternately, the keg can be kept at ambient temperature and served using a "jockey box", consisting of a cooler with beer coils ( metal dispensing lines arranged in a coil) and filled with ice, which acts as a heat exchanger to cool the beer to serving temperature by the time it reaches the faucet. European consumers, when not using a party pump, mainly use inline beer chillers, essentially the same concept as a jockey box but using a refrigeration unit instead of ice. Those chillers usually also have their own air compressor for keg pressurization. Other types of kegs Cornelius keg The Cornelius keg (also known as a "Corny keg" or "soda keg") was originally used by the soft drink industry. It's now commonly used to store and dispense beer, especially homebrewed. Cornelius kegs were originally made by Cornelius, Inc., and were used for premix soft drinks. Since the arrival of newer technology such as bag-in-box packages, Cornelius kegs have become largely obsolete in the soft drink industry, and refurbished ones are readily available to hobbyists. Cornelius kegs use two unique types of tap, both very similar to each other, known as ball locks and pin locks. Mini keg 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
