I Kegged for my first time this past Friday. The beer (an Oatmeal Stout) has been sitting at about 55 degrees now for a little less then 72 hours. The Beer was racked from a secondary into the Keg. The keg has been charging at 15 PSI since Friday evening. I have my liquid lines, my Cobra spigot, and my Ball Lock all sitting in a Star Sans Bath. Here's my question. When I go to draw beer from the keg for the first time to sample it to check for proper levels of Carbonization , should I cut the Co Tank down to 5 PSI just to push the beer, or can I leave the PSI at 15? I do realize that once proper Carbonization levels are reached that I can cut the CO PSI down to 5ish PSI just to push the beer, but I am wondering if I should be pushing the beer with the PSI set at 15. Sounds like a lot of pressure just to push beer.
