100% Altesse. Altesse is also known as Roussette locally, hence the name of the Roussette de Bugey AOC. Named after the village, Montagnieu is the only cru in this part of the southern Bugey, comprising 32 contiguous hectares on a steep, southeast-facing slope. The soils are a mix of rocky limestone scree, heavy clay and gravelly marl.  The Peillot vines average 30 years old but get up to 100+ years in some parcel. The vineyard is quite steep and stony and the vines trained individually in the local gobelet sur échalas style. The farming is organic and the harvest by hand. The whole clusters are direct-pressed and fermented with native yeasts in tank; malolactic fermentation generally does not take place (but a tank will occasionally go through it). Aging is on the fine lees in tank only; there is no wood on any of the Peillot wines. The wine generally finishes with a few grams of residual sugar. It is bottled with a light, non-sterile filtration in the spring/summer after the vintage.
