Jemimagold - He is being complimentary to Guy Robert in that what Robert originally composed as Caleche could in no way be the watered down, banal substance that it currently is. Turin is apparently quite a fan of Guy Robert (the Amouge Gold, Dia).
Interestingly, he seems to not be a fan of Fraysse, Caron's current perfumer.
There does seem to be a strong thread of industry cronyism throughout the book, but that's probably the nature of the fragrance industry to begin with.
I expected the writing to be more sophisticated and I expected the quide to be more complete. Many perfumes I'd like to read his/her opinions on are not listed. So, on the one hand, I love reading the reviews, on the other hand, I wish there were more of them to read!
While I agree with some opinions, I agree for different reasons than are listed. I disagree mightily with some other opinions, which is probably a result of experiences in the fragrance industry, cultural nuances, and chemistry.
Overall, I'm glad I purchased it because it's a jumping off point for discussion and evaluation.
