Meritage - An invented term used by California wineries for Bordeaux-style red and white blended wines. Combines "merit" with "heritage" and rhymes with the latter.

For reds, the grapes allowed are Cabernet Sauvignon, Merlot, Cabernet Franc, Petite Verdot and Malbec; for whites, Sauvignon Blanc and Sémillon. Joseph Phelps Insignia and Flora Springs Trilogy are examples of wines whose blends vary each year, with no one grape dominating.
