The book is written by a 3-time UK champion barista Maxwell. If you are bored of the general coffee books which are written in a similar structure from history to origins to roasting & brewing, this book is for you.
The book is written in alphabetic order of coffee vocabularies. As a blogger, this is an excellent reference book. However, if you are a total beginner, I might not suggest this to you. This is more for people who already has a general understanding of specialty coffee.
