The Sangiovese grape is the most widely planted grape in the Montalcino region and is the only permitted grape in the Brunello di Montalcino DOCG. The particular clones of Sangiovese are unique to the Montalcino region and have developed in adaption to that area's specific terroir. The altitude and climate of the Montalcino region has provided an area where Sangiovese ripens more fully and consistently than anywhere else in Tuscany.
