It depends on how much scorching happened & how long it boiled afterwards. I've tasted beers where it's obvious and I'm sure I've tasted slightly scorched beers where it went unnoticed. Sometimes it'll come off as a smoky flavor—well, I've noticed this when I scorched a mash a bit during a temperature ramp.
I hope it was just a bit of scorching. Burnt sugar ain't the greatest flavor of all time.
