Jean-Marie Berthier created this domaine from scratch in 1980 in the north of the appellation. He grows the two classic grape varieties of the Sancerre appellation, Sauvignon Blanc for the whites and Pinot Noir for the rosé and reds on the slopes above Sainte-Gemme-en-Sancerre. He aims for delicate, refreshing wines that reflect their origins in this classic Loire valley region. His 8 or so hectares are fifty-fifty chalky clay and flint and are exposed to long hours of sunlight so his wines have a combination of ripe fruit flavours as well as expressing the lovely, natural, flintiness of Sancerre.
