La Source refers to the natural spring that comes out of Unang's hill top--literally channeled through the house itself and no doubt used as the household water supply for ages--and which is so loaded with calcium that James has to yearly take a hammer to the deposit buildup coming out of the fountain in front of the house. This is the Syrah cuvée and comes from vines growing at 300 meters in the domain's most clay-rich soils, and is surrounded by oak and pine forests. Just over half the wine is raised in older barrels for one year.
