The richness and personality of a soil created over more than two million years by the accumulation of Pyrenean gravel, together with the climate and the flora, make up the precious DNA of the estate. With approximately 100 acres (40 hectares) of vineyard composed of 46 distinct plots, Kirwan continuously enhances the rich potential of its terroir. We adapt our viticulture to our soil and climate.

Located at the gravelly summit of Cantenac, along the river born of thousands of years of erosion, this terroir expresses and reveals its geological riches. A pedological study recently conducted to better understand the composition of the soil confirmed the central role of gravel. Facilitating drainage and warming the soil, it increases the penetration depth of the roots. Clay captures water and preserves its freshness, maintaining much-deeded moisture during heat waves and periods of drought.
