[Deep Water Vineyard - Wadmalaw Island, SC Our address at the end of Bears Bluff Road started as Irvin House Vineyard in 2001. In 2015 Jim and Ann Irvin were instrumental in transitioning their retirement dream into our lifelong dream, and we will forever be grateful. Nestled among the majestic live oaks on Charleston's back porch of Wadmalaw Island, this 48-acre winery and vineyard has something for everyone. We are the only domestic winery in Charleston, South Carolina and should be on the top of your list when visiting the Lowcountry]
