Query: Best single source of wine

This is a great source of information for many aspects of wine. There is a lot of narrative information about wine producing countries, wine producing appellations, varietals, technical growing information, production (as in fermentation or grape crushing), storage, consumption (glasses, bottle aging, etc), and history (people, wineries, wine gods, folklore, myths, etc).Other nice features: Articles frequently reference each other, with the article heading in bold for easy reference. There are great appendixes with wine stats (production, etc).The only thing I didn't like about the book is that there is no pronunciation guide, which to me is a big negative. Overall, I doubt you will find a better (or even close to better) single source of wine information anywhere else. Why didn't I give it 5 stars? It's not exactly a classic, just a great data source.
