Query: I have them all, this is the best...

Of all the publications I've purchased on zymurgy, (brewing), through the years this edition of Palmer is the absolute best bar none. It is the most accurate, thorough, practical, as well as scientific. I like Papazian and Dave Miller but Palmer is the single book you cannot do without. If you're just beginning home brewing or craft-brewing or you're a brew-master at a micro-brewery this book needs to be or is likely already on your bookshelf.
