Organic wines make a natural progression

For the past four years, a group from the Sierra Club in Denver has hosted an annual tasting featuring organic and other eco-friendly wines. Last month, on Earth Day, the dinner attracted even more people than Eddie Hackstaff, the group's treasurer and wine guru, had expected. "Interest is so high. A lot of people didn't realize that so much of it is out there in stores," Mr. Hackstaff says, adding that the group's verdict was clear: "They're good."
