FOB in beer stands for “Fobbing,” which refers to the foaming of beer during its production or dispensing process. This phenomenon can have both positive and negative consequences, depending on when it occurs.
When it comes to fobbing during wort production, it can contribute to oxidation, which can negatively impact the long-term stability of the beer. Wort is the liquid extracted from mashing the malted barley during the brewing process, which is then fermented to produce beer. If the wort foams excessively during production, it can come into contact with oxygen, leading to oxidation. Oxidation can result in off-flavors, diminished aroma, and reduced shelf life for the final beer product.
Fobbing can also occur during the dispensing of beer, especially when using draft systems. In this context, fobbing refers to excessive foaming that happens when the beer is poured into a glass or container. This can be caused by a variety of factors, including temperature, pressure, carbonation levels, and the condition of the draft system.
Excessive fobbing during dispensing can be problematic for several reasons. Firstly, it can result in the loss of beer, as the foam takes up space in the glass or container, reducing the actual volume of liquid. This can be frustrating for both consumers and establishments, as it can lead to wasted product and financial losses.
Moreover, excessive foaming can negatively affect the sensory experience of the beer. While some foam is desirable, as it contributes to the appearance and aroma of the beer, too much foam can make it difficult to enjoy the full flavor and mouthfeel. Additionally, it can make the pouring process more time-consuming and messy, causing inconvenience for bartenders or individuals serving the beer.
To mitigate fobbing issues during dispensing, beer establishments and breweries often take measures to ensure proper carbonation levels, temperature control, and maintain the draft system in good condition. Regular cleaning and maintenance of the draft lines and faucets are crucial to prevent any obstructions or buildup that could lead to excessive foaming.

Fobbing during wort production can contribute to oxidation and negatively impact the long-term stability of the beer. Fobbing during dispensing can result in beer loss, compromised sensory experience, and inconvenience. Therefore, it is essential for breweries and establishments to address fobbing issues through proper carbonation, temperature control, and maintenance of the draft system.
