Sella & Mosca’s I Piani estate in Sardinia constitutes one of the largest contiguous vineyards in Italy and counts itself among the country’s most impressive wineries. Situated in the northwest corner of Sardinia, just inland from the pretty, historic port of Alghero, this 1,600-acre property contains more than 1,200 acres of vines planted to native Sardinian varietals such as Vermentino, Torbato and Canonau.
