Nerello mascalese is a name given to a varieties of red wine grapes named after the Mascali area in Catania, that grown primarily in Sicily and Sardinia. It is grown mainly on the northeastern side of Sicily (near Mascali, where the grape is thought to have originated) and is thought to be superior in quality to the Nerello Cappuccio. There is an experimental vineyard in Agliano Terme, Piedmont, where Nerello has been planted by the winery, Vini Ragerra, and they are credited with being the first to plant and vinify Nerello in this region.
