“More wineries are calling their blends 'meritage.' I suppose it sounds classier, and commands a higher price than if they call blends a 'meritage' instead of just "Rock Solid Red" or "ZCS."

Not that simple I’m afraid.

“To be designated as Meritage, a wine must meet the following standards: 1. It must be a blend of two or more Bordeaux grape varieties-for red wines these are Cabernet Franc, Cabernet Sauvignon, Carmenere, Gros Verdot, Malbec, Merlot, Petit Verdot and St. Macaire; and for whites they're Sauvignon Blanc, Muscadelle and Sémillon (no more than 90 percent of any single variety may go into a Meritage wine); 2. It must be the winery's best wine of its type; 3. It must be produced and bottled by a U.S. Winery from grapes that carry a U.S. appellation; and 4. Its production is limited to a maximum 25,000 cases per vintage.”

As for me it is all about taste. Who cares about names?
