Historical records for Lussac and the Cistercian Abbey of Faise suggest that Château Lyonnat existed in 1615. At that time it belonged to the bishopric and was home to the steward of Faise Abbey. The property already had a substantial estate of 180 hectares. Most of the production was for the Vatican. So Château Lyonnat's wines have been known outside of France for more than four centuries. This property has belonged to the Milhade family since 1961, when the Château was acquired by Damase Milhade. It now occupies 52 hectares in the commune of Lussac, and has the right to the Lussac Saint Emilion appellation. The vines consist of 85% Merlot, 11% Cabernet Sauvignon and 4% Cabernet Franc. The winery and vineyard are managed by Gérard Milhade and his wife Brigitte according to a rigorous quality policy. Hubert de Boüiard, the owner of Château Angélus, joined Château Lyonnat's team as consultant in 2008.

Château Lynnat's wines generally have a deep ruby colour; the nose develops spicy aromas with notes of liquorice and red fruit. The palate is powerful and supple, developing elegantly soft tannins after a few years.
