Not sure how technical this gets as I havent got a copy YET, but the review peaked my curiosity ...
The Coffee Cuppers Handbook, Ted Lingle
a review by Luca Costanzo http://pourquality.blogspot.com/
This is a must have for anyone who cups on any semi-serious level. I would be shocked - shocked - if anyone who purported to call themselves a professional roaster did not own a copy of this book.
The book itself is unashamedly technical and dry. It isnt a thrilling read, nor does it have Promethean tendencies to illuminate the art, but it does make for an extremely useable reference.
Who should buy it: Serious cuppers. And, to borrow a phrase from Derryn Hinch, if you call yourself a professional roaster and you dont own a copy - shame, shame, shame.
