Last week I was at my LHBS and they gave me a pack of Wyeast Lambic blend for free, because it was 10-11 months old. I smacked it and set it aside to see what might happen.
A week later, it's starting to swell.
I wonder if the yeast is dead, and that's the bugs, or if the yeast has survived.
Is there a way to figure out what's growing when I cut it open?
