A California winery is continuing its experiment in aging wine in the ocean off Charleston.

On Tuesday, seven cases of Cabernet Sauvignon submerged in Charleston Harbor last November were brought to shore. One case will remain in the water for another six months.

It was a year ago that Mira Winery of St. Helena, Calif., pulled up four cases of wine that had been aged in the water for three months.

Winemakers have long known that wine recovered from sunken ships has a unique taste and being submerged is thought to have something to do with that.

Mira is working to determine what effect water motion, light, temperature and other factors have on aging wine. The winery is owned by Charleston resident Jim "Bear" Dyke Jr.
