So I'm brewing an AG American IPA today. I add 2 oz of cascade hops once the boil starts. I smell something burning, like incense. I figure it's my mind playing tricks on me. My wife says what's that smell? I look down and one of the hop pellets landed on that little piece of sheet metal Blichmann gives you with their Boilermakers to use as a heat shield, and was glowing red with an ash on the outside. Smeelled just like incense. Very odd.
