Doug Tunnel is a patient man. Barrel-chested, with a powerful voice that gets people’s attention, the owner and winemaker of Oregon’s Brick House Vineyards is at ease telling a story. Eighteen years as a CBS News correspondent have given him experience talking about matters of import, and he settles into the subject of organic grape farming with all the gravity of a newscast. “The whole concept here, from the beginning, was not to make the organic part the way we sold the wine,” he says. “There was no big ‘OG’ on the label. We wanted people to buy the wine because they liked the wine.”
