I'm sure there is a way to fine a sanke, but I'm not going to mess with it.
Yes, I'm positive they are completely thawed out.
Stratification is kind of what I thought. Maybe that would explain the stronger flavor on the alt.
Ron, did your beer pour clear before it froze? Did it clear up over time?
I'm not too terribly worried but I do think it is odd that I am noticing these changes. The haze on the alt was definitely not there prior to freezing.
