Within the Val d'Orcia is a strip of land following the Orcia river between the DOCG zones of Brunello di Montalcino and Vino Nobile di Montepulciano. Here the Sangiovese and Trebbiano-based wines are produced under the Orcia Denominazione di origine controllata (DOC) status. The DOC red wine is composed of at least 60% Sangiovese with other local varieties, such as Abrusco, permitted to fill in the remainder of the blend. The dry white wine and Vin Santo style DOC wines are composed of at least 50% Trebbiano with other local varieties filling out the rest of the blend. All grapes destined for DOC wine production are limited to a maximum harvest yield of 10 tonnes/hectare with the finished wines required to have a minimum alcohol level of at least 12%.[2]
