Hey, I was just searching around for brewers who had issues with scorching. I'm early on in the electric brewing, so basically I've got a 5000w heating element with no way to regular the wattage. I did a 90 minute boil several months back and forever will be wary of scorched wort. Until I get a way to ease up on the wattage, I keep my nose in close vicinity to the boil and frequently turn off the breaker. The 90 minute boil without easing the wattage created the foulest smelling wort I've ever smelt. I went ahead and chilled, pitched yeast, thinking, maybe it's ok, but in the end, I dumped the whole 5 gallons. It was disgusting, but I think unregulated wattage was the culprit.
