I made up a starter of London Ale (WLP005, I think) earlier in the week with the thought of brewing this weekend. Everything with the starter went as planned. However, when I put it on the stir plate, I never saw any activity, which has never happened before. I’ve had the starter in the fridge for about 12 hours now and it’s dropped pretty clear and there’s a pretty normal amount of yeast that has dropped.
Now, the thing that makes me worried is that this was a 14 month old harvested container of yeast. It’s been stored under beer at about 40F for those 14 months.
I also put 1 drop of Fermcap in when boiling the starter…but I’ve always seen bubble activity on the stir plate even when I add this.
I’m going to check the gravity of the starter tomorrow.
What do you think, safe to use or send it down the drain?
