The vineyards of Domaine de Charron prosper on the fawn sands ("sables fauves") of Bas Armagnac, whose origins date back to the end of the Tertiary, when the sea retreated. This siliceous clay coloured by iron oxide makes the personality and is the pride of Bas Armagnac.

A cross-breeding of Folle Blanche and Noah, the Baco variety appears in the AOC Armagnac exclusively. Its increased resistance to diseases makes it an environment-friendly grape, and everybody agrees on the fact that its main quality is its ability to do wonders when exchanging with oakwood along the years of the ageing process in the oak barrels.

The fawn sands being the prefered soil of the Baco, we consider that only a single grape variety Bas Armagnac enables to bring out this unique and perfect match.
