Best as I can tell, no one who has commented on the book actually has it, except the publisher. Well, I do. It is well organized, beautifully laid out, and contains a wealth of information. There is some new content in the book along with reprints of articles from the magazine.If your only coffee interest is homeroasting the book might be considered overkill by some, though in my 30+ years of homeroasting I have yet to hear anyone say "I know too much about coffee." If you are thinking of starting your own coffee business the book is an excellent resource. Roast magazine is geared for the coffee industry and should be critiqued in that light. I subscribe because I find value in the articles. I also get a lot out of reading this and other forums. All these sources bring something to the table, and my coffee is better for it.
