The Castello ColleMassari winery is located in Cinigiano in the foothills of Monte Amiata, about 1050ft (320m) above sea level. It is about 24 miles (39km) to the north-east of Grosseto in the DOC Montecucco, which is famous for its particularly favourable micro-climate. The Castello ColleMassari is not entirely a medieval castle or a feudal seat of power. Its structure is more reminiscent of a fortified hamlet or even a grancia, a type of protected agricultural operation, founded by Cistercian monks and the Santa Maria della Scala Hospital in Siena in the 8th century. During this era, they set up an agricultural system between Siena and the Maremma that consisted of 22 grance, which helps to explain the name Massari. In the Middle Ages, the term massari or massaro referred to a representative of an agricultural organisation, an important part of which was the farmhouse was located in the centre (massa) of the area.
