I'm not sure if I've read every page of this yet, but it feels like I have. This is one of the three most important books any serious student/aficionado of wine should own. (The other two are The World Atlas of Wine and Wine Grapes.) The OCW covers just about everything you would ever want to know about almost every wine topic imaginable. The sheer breadth of information is astonishing. The entries on the "big topics" such as Bordeaux, Burgundy, etc. are very thorough and informative. Some of the longer regional entries, however, could benefit from a standard organizational format. I felt like most entries made the usual progression of subtopics (history, geography, geology/soils, grape varieties, viticulture, vinification, maturation, and trade). However, other entries drifted between subtopics aimlessly, which made it difficult to compare these regions with other regions.
