I'm not sure how it happened exactly. I may not have cleaned it well enough in between batches and had an accumulation of crud. I can't tell you how strong my boil was since I'm using a PWM to control it, but I was boiling ~21%/hr during batch #3 which was the first to has the burnt taste (the first two were boiled at the same rate w/o issue however). I've since found the 15% (1 gph) set point and used that on a batch over the weekend.
