For the perfect pint, beer needs to be at the proper serving temperature and contain the proper level of carbonation. When the correct conditions are in place, you can pour at the proper rate of 2 ounces per second to deliver the perfect pint.
When dispensing draught beer, the goal is to maintain the brewer’s specification of dissolved carbon dioxide in the beer from keg to faucet. Any change in the carbon dioxide level will alter the taste, pouring characteristics and appearance of the beer.
We see beer pumps being widely used today in the U.S. Although beer pumps do have valid use with beer line runs of several hundred feet or extreme vertical ascensions, use in almost all other applications makes the beer extremely susceptible to over-carbonation or foaming. Over-carbonation causes significant waste that, when combined with the expense of beer pump installation and maintenance, far exceeds the cost of blended gas systems that provide much more balanced carbonation.
In systems in which the beer line run requires the gas pressure to be at a level that approaches the safety limit of the keg, beer pumps may be the only option to push the beer from the keg to the faucet. Your NuCO2 representative will work with you and other draught beer technicians to be sure your system is set up to pour the perfect pint.
