In addition to alcohol and carbon dioxide, finished beer contains proteins, carbohydrates and hundreds of other organic compounds. Yeast and bacteria routinely enter draught systems where they feed on beer and attach to draught lines. Minerals also precipitate from beer leaving deposits in lines and fixtures. Within days of installing a brand new draught system, deposits begin to build up on the beer contact surfaces. Without proper cleaning, these deposits soon affect beer flavor and undermine the system’s ability to pour quality beer. When draught systems are properly serviced using the right solutions and procedures outlined in the Draught Beer Quality Manual, line cleaning prevents the buildup of organic material and mineral deposits while eliminating flavorchanging microbes. Thus, a well-designed and diligently executed maintenance plan ensures trouble-free draught system operation and fresh, flavorful beer
How Clean Is Your Beer System?
As a retailer, you may or may not clean your own draught lines, but you have a vested interest in making sure the cleaning is done properly. Clean lines make for quality draught beer that looks good, tastes great and pours without waste. Take the time to review the guidelines on the reverse and monitor your draught line cleaners—no matter who they are—to ensure that your system receives the service it needs to serve you and your customers well. Simple checks like using a straw to scrape the inside of a faucet and checking keg couplers for visible build-up will help to ensure your beer lines are being properly maintained and serviced.
