It's important to keep track of your brewing if you want to improve, or if you want to be able to repeat your successes. Well, this is THE brew journal. I've been brewing for 9+ years and have used many things to keep track of my brew days. BeerSmith works great, but I want a hard copy for reference and something to track each step better. I've tried other logs, made spreadsheets, etc, but NONE of them are as helpful as this log. There are a bunch of great reference sheets and guides that help, even a section on hops with substitution suggestions and basic profiles to help with recipe formulation. The log sheets are very clean looking, with plenty space for all the details of the brew session. There are plenty pages for your entries, so this along with the FANTASTIC construction of the book will ensure you have it for many brew days. I definitely recommend you try it, as I can't see myself using anything else for my hard copies! I've already labeled the inside cover as "Log 1" as I know I'll be buying another when it's full.
