In addition to alcohol and carbon dioxide, finished beer contains proteins, carbohydrates and hundreds of other organic compounds. Yeast and bacteria routinely enter draft systems where they feed on beer and attach to draft lines. Minerals also precipitate from beer, leaving deposits in lines and fixtures.

Within days of installing a brand new draft 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 undertaken using proper solutions and procedures, line cleaning prevents the buildup of organic material and mineral deposits while eliminating flavor-changing microbes. Thus, a well-designed and diligently executed maintenance plan ensures trouble-free draft system operation and fresh, flavorful beer.

As a retailer, you may or may not clean your own draft lines, but you have a vested interest in making sure the cleaning is done properly. Clean lines make for quality draft beer that looks good, tastes great, and pours without waste.
