The white wine made from this grape, with its white skin and flesh is the reason why the appellation is known as the "Blanc de Blancs". The quality of its vineyards comes from the fact that they are east-facing. With vineyard topsoil over a base layer of chalk the vineyards have excellent hydric qualities thus allowing the chardonnay grape to reach their full potential.
