The grapes are picked by hand, destemmed whole or in part and carried by conveyor so they are not crushed, then fermented with their own yeasts in small wooden vats, with pumping-over or punching down by hand. The malolactic runs partly in vat and partly in barrel, and the wine spends 16 to 18 months in barrel, fined or filtered only as the bottling requires. The underground cellar, built in 2005, is vaulted in the manner of Burgundy and ventilated naturally, in stone, lime, brick, wood and hemp, with no cement and no metal reinforcement.
