CFPS Draft Beer Systems and Technology 2

Question 1

What is the purpose of a secondary regulator in a multi-tap draft system?

Accepted Answer

To allow individual pressure adjustment for each keg or beer line

Answer

Secondary regulators allow individual pressure settings for each keg or tower, so beers with different carbonation levels can each be dispensed at their optimal pressure.

Question 2

What must be done after cleaning draft beer lines with a caustic cleaner?

Accepted Answer

Thoroughly rinse lines with clean water to remove all chemical residue

Answer

After caustic line cleaning, lines must be thoroughly rinsed with clean water to remove all chemical residue before beer is served to customers.

Question 3

In a balanced draft system, what two factors primarily determine the correct CO2 serving pressure?

Accepted Answer

The desired carbonation level and beer temperature

Answer

The correct CO2 pressure is determined by the beer's target carbonation level (volumes of CO2) and its serving temperature, as shown on a carbonation equilibrium chart.

Question 4

What is the recommended minimum beer line length for a direct-draw draft system using standard 3/16" vinyl tubing to provide proper flow resistance?

Accepted Answer

5–6 feet

Answer

Beer lines should be at least 5–6 feet of 3/16" tubing to provide adequate resistance to CO2 pressure and prevent uncontrolled foaming at the tap.

Question 5

What gas is most commonly used to dispense standard American ales and lagers in a draft system?

Accepted Answer

100% CO2

Answer

Standard ales and lagers are dispensed using 100% CO2, which both maintains carbonation and provides the pressure needed to push beer from keg to tap.
