If you are just starting out in the wine world, let Kevin Zraly tag along via "The Windows on the World Wine Course" and you won't go wrong. His light approach and expert analysis of all aspects of the wine world are a reassuring voice amid the din of conflicting advice out there in the wine racks.
Zraly, well-known for his superior knowledge in matching wine with food, keeps his book informative, but not overwhelming. The book is written in a breezy and easily read format, with plenty of white space on each page to keep the text, sidebars, margin info, and graphics from overwhelming the reader. And for those who like to know interesting facts about wine, each page has tidbits written in the margins that when dropped correctly during your next wine tasting will bring out the "Oohs" and "Aahs" in the guests.
The only negative to the book is that it can't have it all ways. It is clearly a beginner to intermediate book, and while it is derived from the class in wine that Zraly actually teaches around the country, it lacks the ability to serve as a comprehensive reference. For this reason, I would team this book with Karen MacNeil's "The Wine Bible" - a very comprehensive, yet still easy to understand resource.
