In addition to his estate wines, he operates as a négociant buying fruit from several neighbors to make varietal wines under the Hexagonales label. The Sauvignon Blanc comes from the best slopes overlooking the river Cher. Jean-François ages the wine for five months on its lees to provide it with a rounder structure and richer aromatic profile.
