I brewed up a blonde by BM. used and cooled using a plate chiller. I did a 10 gallon batch. Moved them both over to two kegs. Here is the puzzle. One keg that I have been drinking on is crystal clear, Its about half empty. The other keg only has had maybe 5 glasses drawn off and is still slightly cloudy. Any clue why? Bother are in the same kegerator at 40 degrees.
