Just over 6 hectares along the Dora Baltea, in the Aosta Valley, for a production that does not exceed 20 000 bottles. In Patois, a dialectal variant of the Franco-Provençal language spoken in the Aosta Valley, La Plantze means «terrace». «Terraces» are the vineyards that are typical of the Aosta Valley, which climb up even very steep slopes, at altitudes ranging from 600 to 1000 meters.
