My friend and I brewed two batches together. He couldn't pitch his yeast earlier because he was waiting for his new temp controller to ship from Amazon.
Isn't there always stuff on top of the krausen anyway? The fermentor wasn't crusty. It was washed, wiped down, and sanitized. I watched my friend clean it. Maybe there was some yeast stuck in some of the edges at the bottom of the bucket.
I gave him the idea of auxiliary yeast eating the sugar and he told me that the fermentor had yeast cake on the bottom that he probably didn't completely scrub out. so it makes 100% sense that is it yeast from his previous batch. The previous batch was used US05... it probably already...
Friend brewed, put wort in plastic fermentor, and didn't get around to pitching the yeast until five days later. Opens the lid and sees lots of bubbles on the surface. Infection? Pitch yeast anyway and see what happens?
I ended up getting this water pump. It seems to pump water through fine. Need to test it out with hot liquid

General question about the immersion chiller. I haven't used it yet but I will as soon as I get a free Saturday. I'm looking at the chiller and how it is coiled up and how the copper is collapsed on itself. Wouldn't it be better if the coil is stretched out to increase surface area? I would...
Yes this makes sense! Btw my OG 1.070.
Now it makes me wonder if all these hop schedules for all these recipes considers about 5-10 min cool down time to 170F.
