Gustavo Gonzalez, the winemaker for Mira Winery in St. Helena, Calif., left, and winery president Jim "Bear" Dyke Jr., speak with reporters in Charleston, S.C., on Wednesday, Feb. 20, 2013, about the winery's experiment in wine aging. The winery on Wednesday sank four cases of wine in Charleston Harbor to see what effect the ocean has on aging the wine. Similar experiments with ocean aging have been conducted in Europe.
