This may be one of the most poorly edited books I've ever had to read. Beyond the endless typos, some made worse by lazy spell-checking, there are clouds of meaningless, vague marketing jargon, thickets of clumsy, opaque academese, and plain old bad English. One passage I recall seemed to average an "and/or" per sentence. And then there's this: "...a region which is considered by some to have been a core part of the region for centuries, was excluded from the wine region by officials in Paris attempting to delineate the region..." (p.271). In its nested repetitiveness, this suggests nothing so much as the beginning of Kierkegaard's _Sickness Unto Death_.
The three stars reflect the importance of the topic and the authors' apparently thorough research.
