The regions of the interior and the west coast of Lanzarote are characterized by massive black mountains and mysterious stone circles linked to the wine tradition of the island. The winegrowers of Lanzarote have discovered that the heavy dark volcanic soil, enriched by the turbulent seismic history of the island, is perfect for cultivating vines. These original vineyards are planted in the dark earth and take cover behind the stone walls of a semicircular shape called "souks"; Malvasia produced here is very good.
