Beer Gas Systems

Beer gas lines, like beer lines, accumulate residue and moisture, and can become a source of off-flavors and aromas in draught beer. Lines, regulators, and couplers will harbor microorganisms in time. To prevent spoilage and reduce the risk of foodborne illness, gas lines should be replaced at the same intervals that beer lines are replaced, depending on the line material: every 10 years for polyethylene (PET) and every 1 year for vinyl. Polyethylene replacements for vinyl jumper lines are available and worth the investment. Polyethylene is NSF/FDA approved food grade and therefore less susceptible to microbial contamination. PET is also available in “barrier” tubing which is especially useful in pressurized gas (CO2, N2) applications because it is engineered to be impermeable to gas and therefore incurs no CO2 and N2 loss. Polyethylene is also the most sanitary line material available for beer gas.

The effects of a poorly maintained beer gas system:

• Beer pouring too foamy / wasted beer
• Beer pouring too fast or too slow
• Flat Beer
• Off-flavors, off-aromas (stale, sour, moldy)
• Excess CO2/N2 consumption
• Gas leak (asphyxiation hazard)

If you suspect your beer gas system is not running as clean and efficient as it should, or if you are interested in replacing or upgrading to better food grade quality parts, please contact us to discuss what type of beer gas system best suits your draught beer.
