The Green Wine Summit kicks off in Napa Nov. 29 and 30 at the Marriott. It's not specifically focused on organically grown wine, but many aspects of sustainability are not addressed by organic standards.
In a perfect world, we'd all be on the same page in terms of defining organically grown as a requirement for "green" but it's all part of moving the ball down the field one step at a time from the industry perspective.
From the consumer's perspective, you can vote with your dollars already and ask the industry to move at the speed of light in converting to organic viticulture as quickly as possible.
