Hey Chris,
I have this book too. I'm about 30-40 pages into it now and am very very impressed.
Ray doesn't go into "how to brew" details as he states that readers should already know the basics, but what he dives right into is grain profiles, classes of grain, types of grain, additions, sugars, etc. He goes into great detail about their function, aromas, flavors, etc. He gets right into efficiency formulas and how to calculating your grain bill. He's taken what as seems a bit cumbersome, and has turned it into very simple calculations.
And I'm only on page 40. Great book.
If anyone wants to borrow it when I'm done, not a problem. Just let me know.
Should be through it within the next week or two.
