This is a fantastic book, which I have read cover to cover. It covers Sauternes, its history, the 1855 rankings, the author's rankings based on quality of wine, and a large writeup for every Chautea of worth in the region explaining the history, the wine making methods, and good and bad vintages. This book is by far the best out there, and my professor at Purdue who taught a Wine Appreciation class (Dr. Richard Vine) told me it was the best in his opinion too. Of particular interest is the history of d'Yquem which the author painstakingly covers. He also devotes a huge chapter to the winemaking methods of Sauternes (by Sauternes, I mean Barsac, Sauternes, Bommes, Preignac, etc). He explains picking methods, chapitilzation (spelling?),etc. I almost always consult this book before making a Sauternes purchase. Disappointingly, I would say only about half the time is the vintage I'm looking at covered in the book. Also, he doesn't go much beyond 1994. However, this is still the best book you can get. You WON'T be disappointed.
