Napa Valley's Grgich Hills raises a glass of the good stuff to Mother Earth by farming nearly all 366-acres of its five vineyards biodynamically. Although the notion of planning farm activity in accordance to a celestial calender and treating plants to homeopathic remedies may strike some as daffy, Mother Earth sure ain't complaining. And neither are the drinkers of Grgich Hills' award-winning Merlot, Zinfandel, Chardonnay, Fumé Blanc, Cabernet Sauvignon, and Violetta. In 2006, Grgich Hills Estate began operating almost fully on solar power. Like biodynamic agriculture's cosmic principles, the yearly energy savings reaped from this project are slightly out of this world: an estimated $70,000.
