I have had a bad attitude about Carolina wines. As much fun as it is to eat and drink local, my experiences w/ Shelton Vineyards and Biltmore wines (both in NC) has led me to believe that red clay and hot humid weather is just possibly not the best terroir for wine ;-)
But...VVV donated a zillion bottles of Merlot (06 I think) to be prizes at a Greenville 5k, and I'll be damned...it wasn't bad. I rarely drink Merlot, but most of the cheap California ones I've been served have been simple and sweet. The VVV wine wasn't a world beater, but it had some interesting tastes and was not sweet.
The winery is just north of Hwy 11 in the general area of Table Rock. Their website says they do tastings.
