Possibly the best of Virginia wineries, is Valhalla Vineyards. Located at the top of a 2,000-foot mountain overlooking Roanoke Valley - the scenery is stunning and the microclimate perfect for the growing of grapes. The soil in this area is set apart by its richness in granite.
There are some truly great wines in their catalogue, which they'll be happy to present to you on a visit. Names to watch for are Row Ten - a blend of French Chardonnay and Rhone Viognier, Dry Ros - a blend of Syrah and Cabernet Franc, Gotterdammerung - one of Cabernet Franc and Merlot, and Norton. This latter is considered an American native. The stock was almost completely destroyed during Prohibition, but ever so slowly it's been making a comeback. If you haven't tried Norton yet, this is the place to do so.
