I purchased this little book as a gift for a friend after I bought it for myself. It's a good little introduction to many champagne houses, both well known and less so. Unfortunately the information on individual houses/producers is far too succint to deliver any real knowledge about background, history, and - more importantly - what the wines taste like. However, what I found really valuable is the little "In the Details" or "Words from the Wise" sections which spring up all over the book; they provide precious information on many topics which are often disregarded, such as the perfect serving temperature, the stages of ageing, how different blends affect the wines, etc. Really worth adding it to your cart!
This is a good little (144 page) introduction to the wines of the Champagne region, although it's let down by a poor grasp of punctuation. Comma splices abound and judging by the author's blog at www.champagneguru.co,uk he writes like this all the time. A semicolon here and there would vastly improve the flow and sense of the text.
Worth a look, but The Finest Wines of Champagne by Michael Edwards is a more rewarding book, in my opinion.
