Well I'm currently boiling my first BIAB and had some problems. First off I misinterpreted the process and put my grains in the bag in cold water in my BK and began heating. I misread my thermometer and went 8 degrees over my mash temp to 160f. I wasn't to worried about that and I thought everything was going well until my mash was over and I went to lift the bag. It burned and broke. I had to transfer everything to my ferment bucket with my extra bag(thank god i had one). Then clean my scorched pot out and transfer back. So it prob is going to have some oxydation from moving it. I tasted it and it tasted fine. Possibly a litle burned but hard to tell. My main concern is the nylon burning. Is that going to poison my beer? I guess there has to be first time mistakes for everything. Hopefilly I don't have to dump it.i
