Almost all of the vineyards produce our most representative wine: Riserva Ducale Oro Chianti Classico Gran Selezione. Greppone Mazzi consists in an eighteenth-cen- tury villa, whose vines grow in arid, almost drou- ght-like soil that drains well. This habitat is na- tural for a particular type of Sangiovese, known as Sangiovese Grosso, which is referred to locally as Brunello di Montalcino. Solatia, in Monteriggioni, has all the qualities needed to produce a Tuscan Chardonnay with a unique expression due to the distinctive terroir. We were one of the first producers to believe that it was possible to make a top Chardonnay in Tu- scany. Certain vineyards are planted with Pinot Grigio, which enjoys optimal soil and microcli- mate conditions here. The cellar is equipped with technology aimed at the specific requirements of white winemaking.
