CFPS Draft Beer Systems and Technology

Question 1

What is the primary function of a glycol chiller in a long-draw draft system?

Accepted Answer

To maintain beer temperature through long beer lines via chilled glycol

Answer

A glycol chiller circulates chilled glycol through insulated trunk lines to keep beer cold over long distances from a remote cooler to the tap.

Question 2

How often should draft beer lines be cleaned according to best practices recognized by the Cicerone Certification Program?

Accepted Answer

Every two weeks

Answer

Best practices call for cleaning draft lines at least every two weeks to prevent yeast, bacteria, and beer stone buildup that causes off-flavors.

Question 3

What type of gas blend is typically used to dispense nitrogenated stouts such as Guinness?

Accepted Answer

75% nitrogen and 25% CO2

Answer

Nitrogenated stouts use a 75/25 nitrogen-to-CO2 blend, which creates their signature creamy texture and tight cascading bubbles without overcarbonating the beer.

Question 4

What is the purpose of a FOB (Foam on Beer) detector in a draft system?

Accepted Answer

To stop gas flow when a keg kicks, preventing foam and beer waste

Answer

A FOB detector stops gas from entering the beer line when a keg empties, keeping lines primed and dramatically reducing foam and waste during keg changes.

Question 5

Accepted Answer

Type D (American Sankey)

Answer

Type D (American Sankey) is the standard coupler used with virtually all American domestic kegs, including most US craft brewery products.
