The name comes from three grapes used for this wine - 40% White Gamay (the former name of Chardonnay), 40% Poulsard and 20% Savagnin. The grapes are planted together as "complantées" - an old wine-growing method whereby a mixture of grape varieties are planted side by side in the same plot.

Southwest exposure on limestone Lias marls with some scree. Biodynamic vines inspected and certified by Demeter France since 2003: use of horn dung (500P), silica (501) and herbal tea treatments.

Slow pressing of the 3 grape varieties together. Fermentation and ageing in oak barrels with no added $SO_2$, regular topping-up and bottling seven months after harvest on a "flower" day according to the lunar calendar. So around 6 months of ageing in the used oak.
