Born from a decree of July 31, 1937, the Côtes du Jura appellation is the most extensive of the Jurassian appellations. It extends from the north to the south of the vineyard, which gives it a great number of contrasts of terroir.

 The soils are stony, not very thick, made of a mixture of marl (grey marl from the Lias in the upper slopes), clay and limestone scree, coming from the limestone ledge on the slopes, and a mixture of marl (iridescent red and green marl from the Triassic period at the bottom of the slopes), clay and limestone on the flats and the gentle slopes

 Aged in oak barrels for about 4 years, it takes the time to concentrate the aromas so dear to this grape variety The permeability of the barrel allows part of the wine to evaporate No topping up is allowed, so the barrel remains incomplete Thus, a veil of natural yeast forms on the surface of the wine and contributes to develop these aromas so close to a Vin Jaune
