What should be the contact time for cleaning a draft beer system with a cleaning solution?

The recommended contact time for cleaning a draft beer system with a cleaning solution is typically around 20 minutes. This duration ensures that the cleaning agent has adequate time to effectively dissolve and remove beer stone, yeast, sediment, and other residues that may have built up in the system.

Cleaning a draft system is crucial because any contaminants can negatively affect the taste and quality of the beer being served. The 20-minute contact time allows the cleaner to penetrate the surfaces and facilitate a thorough cleaning, ensuring that all components of the beer line, including faucets, couplers, and tubing, are properly sanitized.

Shorter contact times may not achieve the same level of cleanliness, leaving behind stubborn deposits that can lead to off-flavors and hygiene issues. Therefore, adhering to this specific cleaning time is essential for maintaining a high standard of draft beer quality.
