Merlot is a black-berry vine, whose name derives from the particular predilection that has its blackbird for its berries, it comes from the Gironde, in the South-West of France, and in particular from the Bordeaux area from which they are born (in a blend with Cabernet) some of the most prestigious wines in the world (Château Lafitte-Rothschild, Château Latour, Château Margaux). Château Petrus and Masseto are two examples of prestigious wines made exclusively from Merlot grapes. Merlot and chardonnay are among the so-called "international" French varieties, the most cultivated in every part of the world, thanks to their high adaptability.
