Chateau de Gayon is an estate located in Southwestern France, near the Pyrenees Mountains. The castle dates back to the 13th century, years before the birth of Henry IV. It belongs to the small Madiran appellation. The wines produced are both Madiran, a full-bodied red meant to accompany the hearty meals and cheese of Southwest France, and a white Pacherenc with residual sugars and balanced acidity, drunk as an aperitif and excellent with fois gras.
