Chiavennasca is the local name for a clone of Nebbiolo grown almost exclusively in Lombardia
The name in the local dialect is Chiuinascha, which means 'more marc' (the solid leftover after the grape crushing). This vine has been widely cultivated in the Valtellina area since the 15th century and it is genetically related to Nebbiolo, one of the typical Piedmontese native vines. This variety is part of the vitivinicultural history of its production area and is used in the composition of the Valtellina DOC wines.
