Grotta del Sole operates in Campania, the volcanic heartland of Southern Italy. The winery draws from the region's distinctive terroir and indigenous varieties. Its Greco di Tufo expresses the crisp, mineral character typical of the white grape across Campania's limestone slopes. The Gragnano della Penisola Sorrentina, built from Sciascinoso, and the Montegauro Piedirosso dei Campi Flegrei Riserva showcase the depth and structure that Piedirosso achieves in the Campi Flegrei zone. These wines have been assessed by Wine Enthusiast, Wine Advocate, and Wine Spectator. The portfolio reflects Campania's reputation for aromatic whites and age-worthy reds rooted in volcanic soil.
