I have a few batches that I am trying to knock out as I have had them since last July. I had some family emergencies came up around that time, so I had to put brewing on the back burner (<---- LOL ).
The last two starters I have had good luck with, but this last one I'm worried a bit. I've kept the yeast in the fridge until I was ready to use it. I took the pack out and smacked it and let it set for a few hours, then made my starter wort, cooled it, then pitched the yeast. With the last two starters, I noticed it would be "fizzy" when I would shake the flask and there would be sweat bubbles around the neck, but I didn't see anything different this go around. No sweat bubbles or fizziness at all when I shook it. I don't smell alcohol in it either. Matter of fact, it smells exactly like the Wyeast pack itself The yeast is Wyeast 1335 if that helps. My last two that did good was the 1056.
I have a feeling I may have to buy another pack of yeast, but I thought about cold crashing to see if I have a good sediment layer, then maybe step it up to see if that layer has increased after cold crashing the second time. around.
