Bordeaux estate examines soil water storage as growing seasons become hotter and drier

Decanter reports that Château Calon Ségur in Bordeaux is examining how its soils cope with warmer, drier growing seasons. Director Vincent Millet is focusing on the water-holding capacity of clay beneath the estate’s gravel. The report contrasts those clay-bearing soils with sandy areas where vines suffer under dry conditions. It also identifies a reserve that collects winter rainwater as a possible irrigation resource, if irrigation becomes necessary. Any such use would depend on authorization and the age of the vines.
