Nishk described Kegerator, a portmanteau of keg and refrigerator, a refrigerator that has been designed or altered to store and dispense kegs. The kegerators keeps the keg in a refrigerated environment and uses CO2 to pressurize and dispense beverages from the keg. This keeps the contents of the keg fresh and carbonated for an extended period of time, on average up to 60 days. Kegerators are specifically designed and available for both commercial and residential use, however, a common refrigerator can be reconfigured into a kegerator with a kegerator conversion kit. Not all standard refrigerators have enough room for a keg, so kegerators are designed in a manner that will allow one or more kegs to fit inside along with the dispensing system. Kegerators are typically used to dispense draft beer, but are also gaining popularity for dispensing wine, cold brew coffee, and kombucha with certain modifications. Components The kegerator contains the following components: Stainless steel keg CO2 cylinder CO2 pressure regulator, with inlet and outlet pressure gauges Keg Coupler (Also known as a Keg Tap) Beer and air Line Tower Drip tray Shank Faucet Faucet handle A crucial part of any draft beer system is the keg coupler, the part inside the kegerator that taps the keg. Different types of kegs require different keg couplers, so considering what you plan on serving is important in order to purchase the appropriate coupler. System D (U.S. Sankey) — standard for North American beer System S (European Sankey) — most common for European beer (Beck's, Heineken, Amstel, Stella Artois) System U — used for stout and ale by a few breweries in UK/Ireland (Guinness, Harp) System G — used by some breweries in UK/Ireland, and in the United States by Anchor Brewing System A — chiefly used by breweries in Germany (Warsteiner, Paulaner, Hacker Pschorr) System M — used by some German breweries (Schneider, Einbecker) Pin and ball lock home brew keg taps — designed to work with Cornelius kegs. The D, S, U and G couplers are secured to the keg by twisting them in place (like a screw). The A System coupler is often called a "German Slider" because, unlike the other couplers, it slides in place and can be secured at any angle. The M-coupler also slides onto the keg, but it taps different brands than the German Slider. Homebrew couplers are different in that they have a separate
