The 10 hectares of vineyards are split between three Grands Crus (Valmur, Blanchot and Les Clos) and six Premiers Crus (Montée de Tonnerre, Vaillons, Butteaux, Chapelot, Montmains and Forêt.) They also produce a Village Chablis (first made in 2007) from vines at the base of Montée de Tonnerre. and a Petit Chablis from 2014 onwards from vines located on the plateau above Grand Cru Les Clos.
The estate’s three Grands Crus, Petit Chablis, Village Chablis, Montée de Tonnerre and Chapelot all come from the right bank of Chablis, dominated by Kimmeridgian limestone soil. All are southwest-facing and therefore produce fuller-bodied, riper-styled Chablis. The remaining Premiers Crus of Montmains, Vaillons, Butteaux and Forêt are on the cooler left bank of Chablis, producing leaner and more saline-driven, mineral wines.
Their largest holdings are in the Premier Cru Montée de Tonnerre, with 3.12 hectares spread across 10 different plots.
Yields are kept low, by Chablis standards. Each year they carry out green harvests (reducing the number of clusters per vine), while at the same time attempting to provide each cluster enough space to mature unimpeded. All the vines are then hand harvested.
