CHARLESTON — A California winery is recovering four cases of Cabernet Sauvignon that have aged on the floor of Charleston Harbor for the past three months.

Mira Winery of St. Helena, Calif., placed the bottles of wine in yellow steel mesh cages and then submerged them offshore in an undisclosed location back in February.

Today, the divers head out to recover the wine so the winery can judge the effects of ocean aging. Winemakers have long known wine recovered from sunken ships has a unique taste and the ocean is thought to have something to do with that.

There have been similar experiments with ocean aging of wine both in Europe and on the West Coast.
