I am brand new to kegging, just a couple of weekends ago I kegged my first batch. Everything went pretty well. After racking to the cleaned keg, I cold crashed the beer in the keg to about 38 degrees, and once cold and after venting the oxygen out then did the shaking the keg trick to get it carbonated quickly. I used about 20 psi to force carbonate/shake, and then I left it at a steady 11 psi.
After about a week though, I’ve found that the first pour comes out very smoothly with a nice head and carbonation. The second pour is almost all foam. Perfect pour to serious foam. And it did not do this at first at all.
I have 5 feet of liquid line between the keg and shank. The fridge remains at about 38 degrees. And I replaced all the o-rings prior to using the keg.
Any ideas out there in brewland?
