So I'm brewing an IPA today and made a starter last night from a vial of expired yeast, hoping I could get it to come alive and ferment my brew today.
I made about 1.8L starter using DME and some yeast nutrient, boiled 10 minutes and have a gravity of 1.048. I let it cool to ambient before pitching the yeast. The yeast is White Labs California Ale. It expired on 1/28/10.
I got up this morning and checked the gravity again, and it was still 1.048. I expected it to go down a few points at least.
Are my yeasties completely dead, or should I be more patient? Would you advise me to get more yeast for my brew today?
