Heroic vineyards are located on small islands or in areas subject to hydrogeological instability or whose conditions make mechanisation at least almost impossible. In all cases, these are extremely difficult conditions compared to traditional viticulture.
Heroic viticulture, therefore, is generally practiced in the mountains. Vineyards cultivated in this way must stand on terraces or steps or have a minimum slope of 30 per cent at a minimum altitude of 500m
