I've got the 2004 edition.
The authors are (IIRC) ex ghost writers for others, who decided it was time to emerge from the shadows.
The aim appears to be to define and describe the best wines in the region without getting to caught up in vintage variations. The style is relatively hard-hitting (for wine authors that is
). A good 700 pages of A5 size info. There's a lot there for the money.
The main section for each region discusses recent vintages, a quick overview section, then producer by producer profiles of the best wines (in their opinion), with contact details. Other wines of note are simply listed at the end of each chapter, along with a few (IMO pointless) lists e.g. 10 fine german whites not from riesling. No tasting notes supplied, but vibes given about wines in general and occasionally referring to a particular vintage or run of vintages.
So although it's an annual, this isn't a book that is particularly vintage focused. I suspect it's one where you might buy the latest version and throw away the one you have.
IMO I think it's got some merit - particularly in the focus at the top end of the market. I have referred to it, but I'm not necessarily convinced it's better than (say) Hugh Johnsons pocket book.
Might also be a little Euro-centric (I believe they're both brits)
Recommendation? Buy if it gets reduced to the point you fancy a gamble, but IMO it doesn't have to be the latest version. I got my 2004 edition about 2 years ago in a charity shop for £3.
