I've been browsing around in Dara Moskowitz Gumdahl's entertaining book, Drink This: Wine Made Simple. If you have even a casual interest in wine, pick-up a copy. Funny and informative, the book resolves many mysteries surrounding the selection and consumption of wine. In fact, there are many "light bulb moments" in Drink This. Read this book and adjectives applied to wine, such as "flabby" or "lean", will suddenly become meaningful to you.
There is also a fair bit of wine-related history salted throughout the various chapters. The history is presented in a very interesting manner and is wonderful means of making the information about the wine itself more memorable.
Drink This is a useful and enjoyable book. It is definitely recommended reading.
