Lately I have been having a problem with carbonating my lighter beers with bottling. I force carb at 17psi for a few days, then bring down to about 6psi for bottling after I have released some pressure. No matter what I do, the foaming is crazy. Used to never have this problem but my last 2 lighter beers I have barely been able to bottle. I know I may have to get a second regulator but any help would be great.
