I stumbled across a copy of Mastering Homebrew by Randy Mosher copyright 2015 and find it to be more helpful to me than other brewing books I’ve read.
I like the challenge of developing my own recipes and this book makes it easier.
The charts and illustrations are more useful and the information is arranged to show relationships between different kinds of hops and malts for example or the illustrations showing how to modify different types of beers that make it simpler to formulate my own recipes.
I would recommend it to any beginner or intermediate brewer.
I have this book, and while I have not read it in detail yet, when I was browsing it at the book store I was like OH MY GOD, FINALLY someone put a great book out there. I would say it’s best for intermediate to advanced homebrewers. But I suppose it would help if I would actually pull it out and read the thing now.
