The issue with developing a list is that brewers are very reluctant in releasing this information since their recipes are proprietary. At this time, particularly craft brews, call brewery and ask for their carbonation level of the product in volumes. Tell them that you need to know this so that you can attempt to balance your system as close as possible.

The majority of the ales and lagers you will find will be in the 2.5 V/V range. A 2.5 v/v product @ 38 F requires slightly more than 11 PSIG for equilibrium of gas in the keg plus up to two PSIG additional "push pressure for dispensing . Thus, apply 13 PSIG to keg while dispensing. This equilibrium pressure guideline can be located on the Zahm-Nagel website.

For every two degree temperature change, adjust pressure one pound up for warmer, one down for colder. For elevation, adjust one pound for every 2000' above 1000'.
