A delightful sparkling wine built exclusively from Chardonnay (younger vines of 20 years of age) harvested from parcels in the village of Serrières on the border with Pierreclos.  The vineyards are west facing and are planted to sandy soils.  Only 6,000 bottles are produced annually.  Depending on vintage conditions, the malolactic fermentation is sometimes blocked in order to maintain the proper high level of acidity.  The dosage is minimal so as to produce a bone-dry, brightly effervescent cuvée.
