Question: 1 / 400

What is the name for the part of a draft system that automatically stops the flow of beer when the keg empties?

beer pump

coupler

faucet

FOB

The FOB (foam on beer) is a device used in draft systems that automatically detects when a keg is empty and shuts off the flow of beer to prevent the dispense of foam. This is important because it ensures that customers receive a full and properly poured beer rather than a foamy and potentially flat one. The other options, while all involved in the draft system, do not have the specific function of stopping the flow of beer when the keg is empty. A beer pump is used to pressurize the keg and push the beer through the system, a coupler connects the keg to the gas and beer lines, and a faucet dispenses the beer into a glass. None of these components have the ability to detect when a keg is empty and shut off the flow of beer like the FOB does.
