This is really strange...
I made a starter of Ringwood from a slant using my stir plate. That seemed to go well. It was a 1L starter, and after 2 days, I stopped the stir plate, and there was a few mm thick yeast cake after crashing in the fridge for 2 days.
I brewed this weekend, and let the flask sit out at room temperature the whole time. I pitched the Ringwood into 5g of well-aerated wort, and S-05 into another 5g, placed the fermenters in the fermentation chamber at 18C, and walked away.
That was Saturday. On Sunday morning I had a nice krausen in the S-05, but nothing in the Ringwood. This morning...nothing in the Ringwood. I ended up pitching S-05 into the Ringwood this morning to try to salvage it.
Ideas?
