Grottolo is a wine made from vineyards located 300 metres above sea level with different exposures and soil compositions: fractured sandstone, tuffaceous marly-calcareous clays. The just-harvested grapes are destemmed and the must is immediately separated from the skins. Vinification is in steel at a controlled temperature of between 12°C and 15°C. It remains in steel tubs for five months to naturally settle, followed by two months of aging in the bottle.
