Located between the 44th and the 45th parallel, the Haute-Serre vineyards enjoy a privileged location halfway between the Atlantic Ocean, the Mediterranean Sea and the Pyrenees Mountains. With a natural alchemy of various criteria - geology, soil depth, altitude and distance to the river Lot - Haute-Serre is composed of a complex terroir of clay and kimmeridgien limestone, favourable to producing great wines for ageing. On the hills, 300m above sea level, the limestone plateau ismade of stones coated with red clay, more or less mixed in the subsoil with blue clay and occasionally covered by a siderolithic formation rich in ferruginous concretions.
It is this feature that gives the great finesse often attributed to Château de Haute-Serre wines. The average annual temperature is 18.7º C. The nights are very cold. The average annual rainfall is 788mm.
This exceptional terroir particularly favourable to the growing of Malbec is also eminently suitable for to the production of great whites. Indeed, the major French whites are most often grown on siderolithic soils.
Convinced of the potential of the soil, Bertrand-Gabriel Vigouroux quickly chose to plant Chardonnay in Haute-Serre, obtaining wines of great elegance.
Haute-Serre, 10 minutes from Lalbenque, is also a truffle terroir. Bertrand-Gabriel Vigouroux planted 1000 truffles oaks to harvest the famous Tuber Melanosporum.
