I’ve read many brewing books, I’ve eclipsed two full shelves of them, and few excite me anymore. But Brewing Local: American-Grown Beer by Stan Hieronymus stands out as one of the more interesting ones. Most books about brewing are either introductory, very advanced, highly specific, or vague and generic.
Brewing Local stands out from all those by being specific in one unique area and covering a wide variety in that area. Instead of telling you how to make a Saison or just rattling off a list of recipes Hieronymus presents a great deal of flexibility and unique ingredients.
