I brewed a hefeweizen last Sunday, OG was 0156. The first 30 hrs of fermentation were the most insane I've seen.
At one point, the blow off tube was clogged and pressure was threatening to blow off the lid. You could hear it whistling every couple minutes then it would blast through to blow off and produce a flurry in the jug. I cleaned out the tube twice.
After 9 days it's sitting at .020, it should be around 15 right?
I just emptied out the jug I was using with the blow off tube, there was a decent amount of trub in it. Is it possible that the aggressive fermentation blew out some of the yeast?
