The area was granted DOCG status in 1990. In 2015 there were 86 hectares (213 acres) of vineyards located north of Vercelli on steep, south-facing slopes at a height of 270–400 meters (900–1300ft). They are centered around the commune of Gattinara and stretch westward towards the Alps. This winemaking zone enjoys a continental climate and the vines grow on iron-rich gravel soils of volcanic origin, with traces of carbonate, calcium and magnesium. These unique soils, combined with the ideal microclimate, yield excellent Nebbiolo grapes.
