I'm an all-grain brewer and finally encountered my first stuck fermentation after 80 batches. My OG is 1.072 and I have made this recipe before and I usually get an FG of 1.021. But my FG has been stuck at 1.042 for three straight days now. I'm not too worried about what caused this at the moment but more wondering if my solution can possibly bring me to my desired 1.021 FG. I have a 15 gallon conical fermenter with 12.5 gallons of wort. My thinking is to cold crash with my glycol chiller and drop the yeast and then dump it. Then gradually warm up the wort to around 68 degrees and pitch some new yeast and hopefully that will eat up the 1.042 wort. Sort of like starting from scratch but instead my new OG is now 1.042! Sooooo...is my thinking flawed and am I missing something?!?
