Red Blends. In general, blended wine consists of a blend of several varieties. Naturally, the varieties used are different depending on the region, as is the proportion in which they blend – a proportion that is usually a closely guarded secret from each producer, since it strongly determines its style and identity. The most famous in the world is the classic Bordeaux blend - the blend between Cabernet Sauvignon, Merlot, Cabernet Franc and Petit Verdeau. Other appeals in France, however, also produce blended wines - for example, the Rhône Valley, where the main actors in the blend are Grenache, Syrah, Murveder and Senso. In the fabled Châteauneuf-du-Pape appellation, things are taken to the extreme, with red blends sometimes containing up to 13 different varieties. The region of Champagne is no less known - Chardonnay, Pinot Noir and Pinot Munni are often involved in the blend. There is a slight difference here though - the blend is between red and white grape varieties.
