I have had four editions of this book and it is very concise guide to selecting wines. Ratings identify best values (shaded stars) and Johnson includes advice on when a specific vintage is "a point" (ready to drink). He is at his best with French wines and one chapter focuses exclusively on Bordeaux. One fault: the review of California wines is not very comprehensive. The simple rating system of one to four stars is realistic and leaves room for your own judgment. I recommend this book.
