Thursday night I made a starter for a stout I'm brewing this weekend.
150g DME and 1.5l water, brought to boil and cooled to ~70f.
Pitched vial of yeast, WPL004 Irish Ale Yeast, at the same temp, had been in my fridge for a few days prior.
Next morning, no activity. That evening, no activity. This morning, no activity.
No krausen, no yeast in suspension other than caused by the stir plate.
Check the gravity just to be sure...1.004
I thought I had gotten a bad vial but apparently something has happened. Also, no noticeable increase in yeast volume.
