Down to Earth: A Seasonal Tour of Sustainable Winegrowing in California

Has anyone read a new book titled Down to Earth: A Seasonal Tour of Sustainable Winegrowing in California? It highlights several California wineries. Any ideas who was included?

This page lists the wineries featured: http://www.discovercaliforniawines.com/downtoearth/

Interesting mix of wineries, from smaller operations like Ampelos and Navarro to gigantic places like Gallo and Delicato.

FWIW, I don’t think I’ve ever talked with a winegrape grower who liked the term “sustainable” - one of many wine-related terms terms that means whatever you want it to mean, so in the end it means nothing at all.
