Week Six: Hugh Johnson and Jancis Robisnon. The World Atlas of Wine.

Every wine enthusiast should refer to this amazing book full of detailed maps of the world's appellations. The number of California AVAs has grown rapidly in recent years as growers have identified the specific soils and microclimates of smaller areas of land. AVAs create a political and market identity for growers' fruit that can help to distinguish the resulting wines (if not in the glass, then at least on the label!).

In the picture: Randall Grahm of Bonny Doon Vineyard speaks about terroir and his sense that wine should be a representation of place.
