Irrouléguy is a small but historically rich wine region located in the French Basque Country, near the Spanish border. Wine production in the area dates back to the 3rd century and was further developed by monks in the Middle Ages, who built terraces on the steep mountain slopes to grow vines.

The vineyards lie on the slopes of the Pyrenees at elevations of up to 400 meters and are characterized by soils rich in schist and sandstone, which provide excellent drainage and contribute a distinctive minerality to the wines. The climate is a mix of mountain, Atlantic, and continental influences, offering a balance between freshness and ripeness in the grapes.

Irrouléguy is one of the few French appellations where Basque grape varieties still play a key role. The red and rosé wines are typically made from Tannat, Cabernet Franc, and the local strain of Cabernet Sauvignon, while the white wines are produced from Gros Manseng, Petit Manseng, and Courbu. The combination of traditional craftsmanship, unique terroir, and indigenous grapes makes Irrouléguy one of the most authentic and characterful wine regions in France.
