Understanding Draft Dispensing

To appreciate the craft of serving the perfect pint, one must first recognize the intricacies of a draft beer system. The design and components built in each of these systems are pivotal in ensuring the optimal delivery of draft beer to the glass.

Components of a Draft Beer System

Draft beer systems consist of several key parts, each crucial for precise and quality beer dispensing.

At the heart of the system is the keg, where the beer is stored under pressure. From the keg, the CO2 tank provides the necessary pressure to push the beer through the beer lines.

These lines are often connected to a keg coupler that taps into the keg. Moving the draft beer systems along, the draft beer tower is where the beverage finally exits the system through the faucet and into the glass.

Proper temperature is maintained by the refrigeration unit, and the regulators ensure that the correct pressure is applied for a balanced beer flow.

The intricate design of a draft beer system is engineered to preserve the beer's integrity from keg to glass.
