100% Altesse. Altesse is also known as Roussette locally, hence the name of the Roussette de Bugey AOC. Montagnieu is a hilltop village and 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 parcels and are gobelet-trained in local 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. 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.
