Contrary to popular belief, this is not a winemaking textbook, rather it is a great look into the process of winemaking as it would pertain to a wine industry employee or wine expert. Anyone seriously trying to make wine should either view 'From Vines to Wines' by Jeff Cox (for home winemakers) or attend UC Davis (for large scale winemakers).
As a Master of Wine student, I have found this to be a great addition to my wine library. Paired with the Oxford Wine Companion and Halliday's 'The Art and Science of Wine' this makes for a solid read.
Pros: beautiful diagrams, great writing, wonderful knowledge
Cons: some topics lack depth, paperback
