What is a draft beer machine called?

Answered by Joseph Vos

A draft machine is commonly referred to as a kegerator. This term is derived from a combination of “keg” and “refrigerator,” which accurately describes the primary function of this device. Kegerators are designed specifically for dispensing draft beer directly from a keg, providing a convenient and efficient way to enjoy the freshness and flavor of beer at home or in commercial settings.

Kegerators are essentially refrigerators that are modified to accommodate kegs and dispense beer. They typically consist of a refrigeration unit, a beer tower, a faucet, and a carbon dioxide (CO2) system. The refrigeration unit keeps the keg at the optimal temperature, ensuring that the beer remains cold and refreshing. The beer tower is connected to the keg via a beer line, which allows the beer to flow from the keg to the faucet. The faucet is where the beer is poured into a glass or mug for consumption.

One of the key components of a kegerator is the CO2 system, which is responsible for pressurizing the keg and pushing the beer through the beer line. Carbon dioxide is commonly used, although some establishments may use a mixture of nitrogen and CO2, known as beer gas, to deliver the beer. The CO2 or beer gas is typically stored in a separate CO2 tank or cylinder, which is connected to the keg via a regulator. The regulator allows for precise control of the pressure, ensuring that the beer is dispensed smoothly and without excessive foam.

Kegerators offer several advantages over other methods of beer dispensing. First and foremost, they provide a consistent and reliable source of draft beer. The beer is stored in a sealed keg, which helps to maintain its quality and freshness for an extended period. This is particularly important for establishments that serve a high volume of beer, as it ensures that each pour is consistent in taste and appearance.

Furthermore, kegerators eliminate the need for individual bottles or cans, reducing waste and the associated costs. They also eliminate the need for frequent restocking, as a single keg can hold a significant amount of beer. This is especially beneficial for home use, as it allows beer enthusiasts to have a variety of beer options readily available without the need for multiple bottles or cans taking up space in the refrigerator.

From a consumer perspective, kegerators offer the opportunity to enjoy draft beer in the comfort of one's own home. The taste and texture of draft beer are often considered superior to that of bottled or canned beer, as draft beer is typically less carbonated and has a smoother mouthfeel. Additionally, the act of pouring a beer from a tap adds an element of enjoyment and ritual that enhances the overall beer-drinking experience.

In my personal experience as a sommelier and brewer, I have witnessed the popularity and convenience of kegerators firsthand. Many enthusiasts and homebrewers invest in kegerators to ensure they can enjoy their favorite beers at their preferred temperature and carbonation levels. It also provides flexibility in terms of hosting gatherings or parties, as a kegerator can be set up in a designated area, allowing guests to serve themselves and experience the joy of pouring their own draft beer.
