Author Andrew Jefford has travelled extensively in each of France's 14 wine regions to investigate the personalities and producers who have masterminded the resurgence of the French wine industry. Producer listings are a significant and important feature of the book as Jefford covers the background of the producers he feels worthy of mention for their contribution to the world of wine and their own individual wines. The book includes research on terroir and its effect on the wines of each region, and how accurately it is reflected by the appellation controlee system.
