Piedra Fluida is the (pet) project of former dog food magnate Felix Becker, who has made it his priority to save venerable vineyards from abandonment. This delicious Listán Blanco comes from the 80-year-old parcel in Granadilla de Abona that is the highest in Europe at 1,680 metres. It partners aromas of iodine, oyster shell and dried herbs with a palate of lemon, wet stones and subtle nutmeg spice and a taut, chiselled, mouth-watering finish.
