Napa Valley, Calif.—Napa Valley’s wine industry has for decades set the pace for New World winegrowing regions, but the well-organized grapegrowers and winemakers there never rest on their laurels. Each year, the Napa Valley Grapegrowers holds its “Ahead of the Curve” seminar to address the issues growers will soon face—or are already experiencing. This year, the seminar focused on a trend that’s becoming more important for high-end growers, as the worldwide wine market increasingly places high value on smaller and smaller geographic areas. The role of the grapegrower in promoting wines made from his property becomes ever more paramount.
