I agree, but a lot depends on the width and height of the FB as well. I boil with a 26gal megapot and use the FB for filtering and it works perfectly for pellet and leaf hop filtering. Its over 19" in diameter with 3/32" holes and sits about 2" off the bottom (almost 3 gallons of liquid sit under it). I have never had any issues with scorching or extraneous color darkening even during rigorous boils. That said, I would expect that if I had a smaller diameter kettle and the FB didn't hold as much liquid under it that I might start seeing some of those issues.
