I've read most of the book now. It's a light read and occasionally interesting, but I suspect it will soon go onto a shelf somewhere and never get picked up again. Ironically, the problem is that the book is astonishingly unopinionated. Here's a quote, from a randomly-flipped to page and a randomly-fingered paragraph:
The problem is, it's all like this: platitudes about how it's important to be mindful of your system, vague statements about the impacts of various decisions, definitions that should be familiar to anyone who has been brewing for more than a few batches, and the occasional handy tip that should be obvious to anybody with access to a homebrew store.
Every ten pages or so, he'll mention something that makes me think, but the bulk of it is stuff I have heard a dozen times before. That's about the information/time density that I get just flipping through the "New Posts" section here. At best, I was hoping that this book would be an interface between the technical books out there (Fix/Briggs/Bamforth/etc) and the homebrew scale ("Okay, so what does trehalose do for me?"). At least, I figured it would be like a brew-session-in-book-form with an extremely experienced brewer.
I don't mean to be harsh, and perhaps I'm missing the point. But the book just seems kind of...empty.
