France's most idiosyncratic and overlooked red wine appellation in the Massif Central foothills above the Lot Valley in Aveyron, producing wines exclusively from Fer Servadou (locally called Mansoi or Brun de Lot) — a variety related to no other known grape. The red sandstone and schist soils of the 'rougier' (red earth) impart an extraordinary iron-mineral character. Marcillac wines have a haunting transparency, wild raspberry character, and an almost medicinal mineral quality unlike any French wine.
