Success! Though, I don't know how much success it'll be...
I mashed a sour-worted Berliner Weiss on 1/6 and kept it at ~110-120F until 1/8. Boiled for 15 minutes on the 8th, killing all the lacto, and racked half to a fermenter. I pitched WLP029 into that batch. The other half, I left in the boil kettle, covered the top with cheesecloth, and left on my covered front stoop overnight. I had plans to place the BK under my rose bushes, but the weather decided that the night of the 8th was a good night to rain, so I had to keep the BK under an overhang. I racked it to a carboy on the morning of the 9th.
I wasn't sure anything was going to happen, because after a few days, there was no activity in the carboy. When I got home from work on the 12th, though, the airlock was going and there was some krausen! Alright! Spontaneous fermentation!
It fermented out and has been sitting there ever since. I've been checking on it every few days, hoping for a pellicle, but nothing... Until this morning! I looked and there was the beginning of a brett-looking pellicle! how cool is this? I have absolutely no idea how it's going to do or how many sugars are still in the beer (i haven't taken an SG reading yet), but the batch I pitched WLP029 into finished at 1.001.
Do you think I should add some simple syrup to the mix to give the bugs something to eat? Should I take a reading now, while the pellicle hasn't covered the surface yet?
Thanks! Sorry for the long-winded post! I'm just stoked that some bugs got in!
