I kegged my ESB several weeks ago and dialed in a low carbonation level to keep it true to style. While it's not excessively carbonated now, it seems as if the level has increased. I just poured some and noticed some large bubbles along with the tiny ones. I typically leave the regulator in the neighborhood of 10 or below to dispense. The keg is kept in a Sanyo 4910, and I believe that the temperature fluctuates with the compressor cycling.
Is this normal? Or is it my imagination? ;-)
