Though the labels bear different first names, they're from the same vineyards, they are all made in the same cellar, following identical principles. New oak doesn't contribute any more than 30% of the cuveé, long ageing with no battonage is standard, and pesticides and herbicides haven't been a part of the family's farmed holdings for generations. No herbicide or fertiliser is used in the vineyard. Harvest and sorting are done manually. Wines are fermented wild in barrel, thereafter raised in oak for 18-21 months, with up to 40% new oak used for the top cuvées. Fined but not filtered. On top of that, the vines mostly carry a decent amount of age - some 60 years plus - all closely tended by hand before what Pierre Boisson calls ‘slow, patient winemaking with not too much oak and minimal lees stirring’.
