As a wine professional in San Francisco I recommend this book to anyone who has considered taking their beginning wine appreciation to the next level. It is a visually engaging and accurate resource, there are dozens of comprehensive maps, and relevent information on virtually all of the world's wine regions. If one is looking for something more intuitive and accessible than the Oxford Companion, this is a great choice.
