53. The applied pressure is also the vehicle for forcing the beer from the keg through the beer lines and into the glass at the dispensing point Many operators mistakenly believe that this is the only function or at least the major function of the applied pressure and therefore the pressure may be decreased or increased at will to facilitate a desired dispensing rate flow rate Because of the effects on the carbonation level of the beer and therefore the quality of the beer itself the pressure must not be changed to achieve a desired change in the flow rate The only acceptable method for adjusting the flow rate is by changing the amount of the restriction or drag in the system with respect to the flowing beer The amount of additional restriction may be adjusted by adding or removing lengths of the main beer lines or adding or removing shorter portions of smaller sized tubing choker lines to the beer lines Part Number STH13 9 10 13 In some beer systems the walk in cooler or storage room is located remotely and on different levels from the dispensing points Under these conditions even with large size beer lines it is often not feasible to dispense beer at an adequate flow rate with normal keg pressures since the drag or resistance of the lines as well as vertical lift that may be required can be sufficient to reduce the flow greatly at these standard pressures In these cases it is often necessary to pressuriz

105. ure Beer is pressurized in the keg by the brewer to his exact specifications which are optimized for the best possible flavor For example under pressurized beer will taste flat and over pressurized beer will taste bitter It therefore follows that the vendor must carefully balance his system to the beer specifications of the brewer in order to dispense the beer with the best possible flavor to his customers Failure to do so can result in poor tasting or foamy beer This is why it is strongly recommended that each keg or beer supply be regulated by its own pressure regulator The optimum pressure for most domestic beer dispensed at normal temperatures and at sea level is 12 to 14 pounds per square inch psi keg pressure 12 Part Number STH13 9 10 Some domestic beers require slightly higher pressure and some imported beers require lower pressure which explains the need for separate pressure regulators for each brand This information is readily available from the beer distributor Areas with higher elevations will require higher keg pressure specifically one psi for each 2 000 ft 609 6 m elevation above sea level This increase in keg pressure is necessary to retain the correct carbonation level in the beer itself since the carbonation level is a function of the absolute pressure and not the difference in pressure between keg and atmospheric which is the pressure maintained by the pressure regulator on the beer system
106. utes Since a small amount of beer is trapped behind the faucet there is a likelihood that this small amount of beer will also warm slightly The result will be that this trapped beer will fracture and produce foam on the first beer dispensed after an extended idle time When all of the slightly warmed beer has been depleted from the faucet and the beer line subsequent beers drawn immediately following the first should produce about the same amount of foam or head but less than the first beer In long draw or remote systems as described above it is essential to refrigerate the beer lines throughout 16 Part Number STH13 9 10 their entire length at about the same temperature as the beer in the cooler Most manufacturers of these systems agree that it is not possible to adequately refrigerate these lines using cold air over distances greater than about 15 ft 4 6 m Therefore these systems utilize a liquid refrigerant line continuously cycling propylene glycol at a temperature below 30 F 1 1 C or other suitable liquid coolant in physical contact with beer lines and with the overall assembly contained in a flexible insulated housing These systems when properly designed and installed generally offer the best and most consistent draught beer product On the other hand an improperly designed installed or maintained system even a rough or damaged gasket can produce shots of foam continuous foam or continuously warm and
