"Chant du Vent" translates to "Song of the Wind", which refers to the whistling noise created by the wind as it hurtles through the vineyard posts. The Satos want this wine, along with the Sur Les Nuages Pinot Noir, to represent their whole farm, so in a way, this is the Siren Song of the Sato vineyard.
It's a richly yet mineral-driven Chardonnay with plenty of weight and flavour. It will drink well now but also reward mid-term cellaring.
