The Dezat family is one of the oldest and most respected wine-growing families in Sancerre, with references to the family dating as far back as 1550.
André Dezat took over the family vineyards in 1948 and became actively involved in promoting the wines of Sancerre. In the 1970's, he was joined by his sons, Louis and Simon. The winery was then modernized with new facilities and gained new impetus, particularly in terms of the production of wines from Sancerre and Pouilly-Fumé. Today, Andre's grandsons Arnaud and Firmin Dezat are the new generation and take the most active role in the family business.

The winery has always focused on striving to produce wines of great quality, with full respect for their typicity and for the environment. As a result, in 2018, the Andre Dezat estate was granted the French official “high environmental value” certification for maintaining a commitment to sustainable farming and biodiversity.

The Andre Dezat estate spans 45 ha of vineyards across various soils rich in "Terres Blanches" (chalk), limestone and "silex" (flint), that bring complexity, purity and fine character to the wines produced. This special terroir, combined with a historical know-how, make Andre Dezat wines sought after and enjoyed more than ever by consumers around the globe.
