kegerator

A kegerator is a refrigerator or refrigerated cabinet configured to store one or more beer kegs and dispense beer through a tap. It combines a cooling system with a kegging system that uses carbon dioxide (CO2) or a CO2/nitrogen blend to push beer through lines to the faucet. Typical components include a keg or multiple kegs, a CO2 regulator and cylinder, gas and beer lines, a beer faucet or taps, a faucet tower or built-in turret, and a drip tray. Temperature control keeps beer cold, usually around 34–38°F (1–3°C).

There are different configurations, including purpose-built kegerators designed for home or commercial use and consumer refrigerators converted with a kegging kit. They can be single-tap or multi-tap and may be freestanding units or integrated builds. Some systems run on a single CO2 source with a manifold for multiple beers.

Operation involves maintaining appropriate pressure so beer flows smoothly from keg to faucet as it is dispensed. This pressure, line length, and line diameter influence foaming and pour quality. Regular cleaning and proper setup are essential for flavor and hygiene.

Maintenance and safety considerations include cleaning and sanitizing beer lines and taps regularly, typically every few weeks, and ensuring all CO2 connections are secure. CO2 is stored under pressure, so careful handling and adequate ventilation are important. Kegerators can require significant space and energy, but offer convenient, consistently served draught beer.
