PROBLEM CAUSE CORRECTION Loose Foam. Large soap-like bubbles that settle quickly. • This is generally the same as the Flat Beer condition. • See the Flat Beer causes above. Off-Taste Beer. Often bitter and bitey; sometimes completely lacking in flavor and zest. May also have an oily or foul odor, which carries an unpleasant taste. Sour Beer. Beer tastes and smells extremely yeasty or moldy. Wild Beer. Beer that is either all foam, or too much foam and not enough liquid. • Improper cleaning of the tap. • Contaminated air line. • Improper type of beer tube • Brush and clean the tap properly. It should be scoured using a detergent, then rinsed clean. • Beer tube should be examined. If contaminated, it should be replaced. • A rubber hose will absorb and retain odors. Try using a plastic tube instead. *General Recommendations for Off-Taste Beer: Beer lines should be flushed after each keg is emptied. Maintain fresh, clean, sanitary conditions around the dispenser. Smoke, cooking odors and disinfectants will harm the taste and flavor of beer. These conditions, as described, may come from an air source or from actual contact with the glass when drawing beer. • Improper transporting of beer kegs. Beer that is delivered on an open truck during high summer temperatures may start a secondary fermentation process. • If possible, have beer kegs delivered in a closed, refrigerated truck. If an open truck is used, cover beer kegs with tarpaulin for protection against summer heat and warm air. • Improper drawing of beer into • Open the faucet quickly and completely. the glass. • Proper foam should be a tight, creamy head, and the collar on the average glass should be 3/4" to 1" high. • Yeast growth or other obstruc- • Check for, and replace any kinked, dented, or tions in the faucet, which is twisted lines from the barrel to the faucet. usually caused by a non-refrig- • Examine for frayed coupling washers behind the erated faucet.

Then adjust the pressure to suit a properly balanced system. The correct beer flow should fill a 10oz. glass in 4 seconds at the proper temperature. • Adjust the CO2 pressure to as low as possible. However, the applied pressure must remain slightly higher than the internal pressure of the beer. No more than 18 lbs. should be applied. The proper amount should be between 10-12psi/lbs. • The colder the beer and the higher the applied CO2 pressure, the more rapid the absorption of CO2 by the beer. This over-carbonates the beer, causing Wild Beer. • Check the pressure regulators periodically to ensure that the operating pressures remain constant.
