I pitched a starter yesterday for my Sweetwater IPA clone that I’m brewing today and I think it went bad. I’m using Wyeast 1968. This morning when I went to swill it, it had formed a solid gelatinous mass on the bottom of the beaker and would not break up. When I picked it up yesterday at my LHBS, I noticed it felt half frozen and when I opened it to pitch the starter, it had a lot of jelly like particles. Is this normal for WYEAST London ESB?
