The portfolio of varietals planted in Sardinian vineyards bears little resemblance to those in any other Italian wine region. Instead, one finds varietals of French and Spanish origin, exemplified by Grenache (called Cannonau here), Carignan (Carignano), Cabernet Sauvignon and Bobal. The most 'Italian' varieties here are Malvasia and Vermentino,
Sardinia's terroir is full of promise for the hopeful vigneron. The combination of hills and plains, coastal regions and inland areas offer useful diversity of topography and mesoclimates. The available soils and bedrocks vary from granite, limestone and sandstone to mineral-rich clays and free-draining sands and gravels. Located between 38 and 41 degrees north, the island lies at the southern edge of European viniculture, but thanks to the cooling effects of the Mediterranean, the maritime climate here is more forgiving than in other regions at this latitude.
