I am force carbing my first batch. It is a light pale ale that I wanted to be pretty sprtizy. I set my regulator to 20# and let it sit @53 degrees for two weeks. The beer pours a great head and has some foam (if I swirl it there are lots of tiny bubbles), but there are no bubbles in the beer itself.
I was disappointed, so I cranked my regulator to 55# and rolled the keg for ~5 minutes. I waited 24 hours. There was more foam, but still nothing in the beer.
At each test I have purged the keg and reduced the regulator to 5# for serving and am using 8' of 3/16" line.
What am I doing wrong?
What do I need to do to get this beer near champagne carbonation?
