Pineau des Charentes, (Pineau Charentais, or simply Pineau) is a regional French aperitif from 1589, made in the départements of Charente, Charente-Maritime and, to a much lesser extent, Dordogne in western France. While popular within the region of production, it is less well-known in other regions of France and somewhat uncommon abroad. It is a fortified wine (mistelle or vin de liqueur), made from a blend of lightly fermented grape must and Cognac eau-de-vie.
It is mainly used as an aperitif and is also amazing with foie gras . It is lovely stuff and connects to a region of France I know well.
It also has the advantage of not being too pricey, most Pineau des Charentes Plessis 75cl is around £10.
Try it this summer.
