As a sommelier and brewer, I have had the opportunity to work with various beer dispensing systems, including FOBs. FOBs, or foam on beer detectors, are crucial components of a beer tap system as they help prevent excessive foam and ensure a perfect pour. However, like any other part of a beer system, FOBs require regular cleaning to maintain their optimal performance and hygiene.
The frequency of cleaning FOBs depends on the specific system and usage. In general, it is recommended to clean FOBs as part of a comprehensive system clean. This means using a recirculating pump to clean the entire system, including the FOBs, beer lines, faucets, and keg couplers. By incorporating FOB cleaning into a larger system clean, you can ensure that all components are thoroughly sanitized.
To keep FOBs in top condition, it is advisable to use a caustic cleaning solution every two weeks. This solution helps remove any built-up residue or bacteria that may affect the functionality of the FOB. Caustic solutions are effective at breaking down organic matter and ensuring a thorough cleaning.
In addition to regular caustic cleanings, it is also essential to conduct acid cleanings for beer dispensing systems every four weeks. Acid cleaning solutions are particularly effective at removing mineral deposits and beerstone, which can accumulate over time and impact the quality of the beer. Acid cleanings help restore the FOBs to their optimal performance and ensure a clean, crisp pour.
In my personal experience, adhering to a regular cleaning schedule for FOBs is crucial to maintaining the quality of the beer and the overall efficiency of the beer system. Neglecting proper cleaning can result in clogged lines, inconsistent pours, and even off-flavors in the beer. Regular cleanings not only improve the taste and appearance of the beer but also extend the lifespan of the FOBs and other components of the system.
To summarize, beer FOBs should be cleaned regularly as part of a comprehensive system clean. Using a recirculating pump, it is recommended to clean FOBs with a caustic solution every two weeks and conduct acid cleanings every four weeks for optimal performance and hygiene. By following this cleaning schedule, you can ensure that your beer is poured perfectly and maintain the overall cleanliness of your beer dispensing system.
