According to the model, I should pick Stan Hieronymus' Brewing Local: American-Grown Beer.
It's my least favorite of his books in an otherwise very strong catalog. It falls victim to the same problem pretty much all of the BP books started falling into around that time where they tried to make the book a jack of all trades and a master of none. The first half of the book has little relation to one another. The encyclopedia of ingredients is good and covers many not covered by other homebrewing books about foraged or homegrown ingredients. The recipes in the back are good. IMO if you brew with garden or foraged ingredients, it's another one to add to the small pile of books on the subject. Otherwise, maybe one to pass.
A great book on the same subject is The Homebrewer's Almanac by the people at Scratch which includes a bunch of their actual ingredients.
