Brunello Di Montalcino - Climate and Geography

Climate and Geography

Montalcino has one of the warmest and driest climates in Tuscany with the grapes in the area ripening up to a week earlier than in nearby Vino Nobile di Montepulciano and Chianti Classico. It is the most arid Tuscan DOCG, receiving an average annual rainfall of around 700 mm, in contrast to the Chianti region which receives an average of 900 mm. As with all of the Northern Hemisphere, the northern slopes receive fewer hours of sunlight and are generally cooler than the southern slopes. Vineyards planted on the northern slopes ripen more slowly and tend to produce wines that are racier and more aromatic. Vineyards on the southern and western slopes receive more intense exposure to sunlight and more maritime winds which produces wines with more power and complexity. The top producers in the area have vineyards on both slopes, and make use of a blend of both styles.

The town of Montalcino is a small medieval village located about 564 metres (1,850 ft) above sea level in the province of Siena. The wine district is centered to the northeast of the village in densely wooden and hilly terrain. Monte Amiata, the highest peak in Southern Tuscany, provides a sheltering influence from the southeast and tempers the region's climate and rainfall. Compared to the nearly 41,000 acres (17,000 ha) of planted land in Chianti, Montalcino is a relatively small wine region with around 3,000 acres (1,200 ha) planted. Vineyards in Montalcino are planted in varied soils-including limestone, clay, schist, volcanic soil and a crumbly marl known as galestro-at altitudes ranging from 149 m to 500 m. This diversity in terroir contributes to the vast range in quality and potential complexity of Brunello di Montalcino.

According to Kerin O’Keefe “although sangiovese excels in select parts of Montalcino, it does not perform as well throughout the whole denomination thanks to the dramatic differences within the large growing area.” O'Keefe is in favor of putting subzones on the labels as this would greatly help consumers understand the stark differences among Brunellos from Montalcino's greatly varied territory, proposing 8 subzones: Montalcino North, Montalcino South, Castelnuovo dell'Abate, Camigliano, Tavernelle, Bosco, Torrenieri, Sant'Angelo.
