The Vineyard
The vineyards at Castello di Brolio, home to Barone Ricasoli, span altitudes from 720 to 1,640 feet (220 to 500 meters) above sea level with predominantly south and southwest exposures. The Mediterranean climate features mild winters with rare snowfalls, hot, dry summers, and annual rainfall averaging 32 inches (813 mm), concentrated in spring and autumn.
Sangiovese is the dominant variety. Extensive zoning research has identified nineteen distinct soil types across the estate, the following five of which are key:
Macigno del Chianti Formation: Sand and rocks with low organic matter at 1,310-1,640 feet (400-500 m) altitude. Vines: Sangiovese, Merlot, Chardonnay.
Scaglia Toscana: Thin, schist-based soil at 1,310-1,640 feet (400-500 m) altitude. Vines: Sangiovese.
Monte Morello Formation: Calcareous clay at 1,150-1,280 feet (350-390 m) altitude. Vines: Sangiovese, Cabernet Sauvignon, Merlot.
Marine Deposit: Sandy sediments and clay at 980-1,150 feet (300-350 m) altitude. Vines: Sangiovese.
Ancient Fluvial Terrace: Silty, clay-based soil at 850-980 feet (260-300 m) altitude. Vines: Sangiovese, Cabernet Sauvignon.
