Draft Beer Serving Essentials

Getting the perfect pour of draft beer isn't just about having the right equipment; it's about mastering the intricacies of temperature and pressure settings, and understanding how to balance the draft system effectively.

Pressure Setting Are Critical For Dispensing Draft Beer

Temperature and Pressure Settings

The temperature and pressure within a draft beer system are critical for maintaining the beer's quality and ensuring the perfect pour.

The ideal serving temperature for most ales is between 36 to 38 degrees Fahrenheit. The kegerator or refrigeration unit is responsible for maintaining these temperatures.

Pressure settings are equally vital.

Commercial dispensers use a CO2 tank to pressurize the beer lines and maintain carbonation in the beer. The pressure must be set according to the type of beer and its corresponding carbonation level, which generally lies between 12 to 14 PSI (pounds per square inch) for most beers.

Balancing the Draft System

Balancing a draft beer system ensures that beer flows smoothly from the keg to the faucet without excessive foam or carbonation issues.

This balance is achieved by considering the length and inside diameter of beer lines, the pressure from the CO2 tank, and the temperature of the beer.

  • Beer lines should be matched with the correct resistance, measured in pounds of resistance per foot, to counter the applied pressure from the CO2 tank.
  • Faucets must be regularly cleaned and maintained to prevent blockages that can affect the beer's flow and quality.

Choosing the Best Kegs and Taps

When outfitting a commercial setting with beer dispensing equipment, a precise selection of kegs and tap towers ensures a smooth pouring experience and customer satisfaction.
