What does 'FOB' stand for in beer systems?

The term 'FOB' in beer systems stands for "Foam on Beer." This term is commonly used in the context of draft beer delivery systems, particularly those utilizing a beer keg system. The purpose of an FOB device is to manage the excess foam produced during the tapping and pouring of draft beer, which can often lead to wasted product and inefficient serving.

When a keg is nearing depletion, an FOB system allows foam to build up in a chamber that is designed to prevent beer from flowing unless the chamber is filled with liquid. This helps to prevent the beer from being poured as foam, ensuring that only liquid reaches the glass. This system ultimately enhances the quality of the pour, maintaining the integrity of the beer and improving the overall serving experience while minimizing waste.

Understanding the function of FOB is crucial for those involved in beer service, as it directly impacts efficiency and customer satisfaction.
