Those who have read the Faber & Faber guides to wine regions such as Burgundy, Alsace and the Rhône valley and expect something similar, may be disappointed, but of course you can't squeeze that much into about 350 pages. What we get instead is a kind of long essay which covers Italy north of Tuscany. Belfrage still manages, almost miraculously, to cover quite a number of producers (including some that are not included in the Slow Food/Gambero Rosso annual guide to Italian wines), and, what's more, he gives you an idea of what's going on. A very useful update almost ten years after Burton Andreson's groundbreaking atlas. If you want to know more, you need to read Italian (and get the regional guides published by Slow Food).
Excellent in depth study of Northern Italian wines. If you want to progress beyond a simple wine guide, then this is as good as it gets. Very detailed, knowledgeable and informative, but written in an engaging and easy-going style. Highly recommended.
