Grapes are harvested off vines planted to rich marine fossil clays originating in the Pliocene era, at altitudes between two and four hundred metres. Chardonnay and Grechetto are separately destemmed, crushed and treated to a cold soak for several hours. Chardonnay is transferred to a selection of 225 litres Alliers and Troncais French oak barrels for two or three weeks of vinification. Batches remain in contact with sedimentery lees for six months while completing full malolactic. The Grechetto component is treated to inoculation in fermenters to retain varietal purity. The finished wine is assembled, bottled and laid to rest for a further ten months ageing under the historic wine cellars at Castello della Sala.
