In the commune of Oger, in the heart of the Côte des Blancs, stands the Domaine Demière Ansiot, a family-run estate cultivating 8.5 hectares of vineyards classified Grand Cru. Winemakers for four generations, today the property is run by Nicolas Demière who, together with his family, manages all stages independently, from production and harvesting to the sale of the cuvées. The vineyards are 100% Chardonnay grapes, they are over 40 years old and 40% of them have a south-eastern exposure, thus benefiting from more sunlight, which allows the grapes to ripen optimally.
