Castello di Volpaia Il Puro Gran Selezione, Chianti Classico DOCG Il Puro or, The Pure, is so named as its made from 100% Sangiovese from the celebrated vineyard Casanova between similarly lauded vineyards of Coltassala and Balifico. Situated at an altitude of 500 metres on south-facing slopes of Volpaia above the sea level. The vineyard is organic and is home to 25 clones of 60-plus-year-old Sangiovese vines indigenous to Volpaia. The number of clones doesnt just give the wine complexity, it preserves the genetic diversity and health of the vines.
