You can find a ‘Bordeaux blend’ all over the world, where ever wine makers harvest Cabernet Sauvignon, Cabernet Franc, Merlot and perhaps Petit Verdot and Malbec.  Blending is the Bordeaux signature, there are single varietal wines here, but they are the exception. Bordeaux blends its whites too, mainly Sauvignon Blanc and Semillon with a touch of Muscadelle.
