Patata Rossa di Colfiorito

Registered as a protected geographical indication in 2014, the Patata Rossa di Colfiorito IGP covers a production zone limited to ten municipalities, primarily within the Marche region, including Foligno and Sefro. This red potato denomination stands out in Italy's registry due to a striking operational contrast: while its geographic boundary is clearly defined, the denomination officially registers zero verified producers. This empty producer registry distinguishes it from neighboring food origins, leaving the legally protected name inactive in practice. For the international observer, this potato variety represents a fully legislated European origin that exists purely as a geographic reservation without active certified commercial output.
