Book excerpt: Featuring a fresh layout, revised maps, and more detail than ever before, the eagerly anticipated seventh edition of Parker's Wine Buyer's Guide offers collectors and amateurs alike the ultimate resource to the world's best wines. In every way, this edition bears out Parker's stated goal: "To make you a more formidable, more confident wine buyer by providing you with sufficient insider's information to permit the wisest possible choice when you make a wine-buying decision." Understanding that buyers on every level appreciate a good deal, Parker separates overvalued bottles from undervalued, with wine prices instantly shifting according to his evaluations. Indifferent to the wine's pedigree, Parker's eminent 100-point rating system allows for independent, consumer-oriented, inside information. The latest edition of Parker's Wine Buyer's Guide includes expanded information on Spain, Portugal, Germany, Australia, Argentina, and Chile, as well as new sections on Israel and Central Europe. As in his previous editions, Parker provides the reassurance of a simple number rating, predictions for future buying potential, and practical overviews of regions and grapes. Altogether, an indispensable resource from the man the Los Angeles Times calls "the most powerful critic of any kind."
