You can't always trust the sommelier, brush up on some serious wine knowledge with Assouline's Bordeaux, Legendary Wines:
"With a history spanning centuries, the Bordeaux region ranks as perhaps the premier winemaking area in the world. As internationally renowned wine expert Michel Dovaz makes clear in this tour of the châteaux of Bordeaux, the true story of this legendary wine begins eons ago, when the earth itself took shape and blessed one part of France with magical soil. This volume presents the fascinating history of the many châteaux that have been operating continuously since the seventeenth century. The author also relates the many steps that go into the creation of these prestigious wines, and presents an essential catalog featuring the wines of 125 châteaux, complete with a glossary, tables of harvest conditions of various years, and tasting notes for recent vintages. For the wine amateur or experienced oenophile, this splendidly photographed volume offers an authoritative guide to the appreciation of this rare treasure."
