In 2010 the Barolo Consorzio introduced the "Menzioni Geografiche Aggiuntive" (additional geographic mentions) also known as "MEGA" or "subzones", after the Barbaresco Consorzio introduced them in 2007. 181 MEGA were officially delimited, of which 170 were vineyard areas and 11 were village designations. Following the introductions of MEGA for Barolo (and Barbaresco) the term Vigna (Italian for vineyard) can be used on labels after its respective MEGA and only if the vineyard is within one of the approved official geographic mentions.
