I'm enjoying this book immensely. This is my second home brewing book (Papazian was the first, about 15 years ago). Like Papazian, "Radical Brewing" includes plenty of lore in addition to hard core brewing info. And like Papazian this book has lots of humor in it. But Mosher's book is much more current, in terms of both information and viewpoint. And the humor is sardonic where Papazian's humor tends to be more goofy and quaint.If anything "Radical Brewing" is slightly less practical than "The Joy of Homebrewing." It seems like Mosher focuses on giving the reader inspiration rather than step-by-step instructions, which is very wise considering how individualized each batch of homebrew is. Papazian has a certain recipe mentality, where Mosher is instead setting forth ideas and techniques. Good stuff, particularly for the intermediate or advanced brewer. Highly recommended.
