Bob Cannard has been farming sustainably for 30 years, providing produce to Alice Waters’ Chez Panisse restaurant in Berkeley. Growing up in the commercial nursery business, he has since developed the natural process approach to agriculture that's used at Green String. He has long been an important member of the sustainable food movement in Northern California.
Fred Cline acquired a love for agriculture and vinifying grapes into wine on summer visits to his grandparents when he was young. He founded Cline Cellars in 1982, and has been growing his grapes the Green String way since 2000.
