I'm more perplexed by her brewery linking to her blog. It's one thing to denigrate homebrewers and homebrewing, it's another to link it back to your brewery. I'm all for private citizens saying whatever dumb crap pops into their head, but this seems like bad business.
I told my wife about the esters-from-hops thing, and she said "What?! I don't know anything about brewing, and even I know esters are from yeast."
