The winery is located in the municipality of Greve in the heart of the Chianti region (province of Florence) in the Italian region of Tuscany. The name (beautiful oak) derives from the lush oak forests that grow here, which also provide protection against cross-contamination from conventional farms. The winery was founded in 1974 by the industrialist Giuseppe (Pepito) Castiglioni through the purchase of a vineyard of one hectare. He set himself the goal of producing wines in the style of Bordeaux and Burgundy. In 1988 his son Sebastiano Cossia Castiglioni converted the cultivation first to certified organic and in 2000 to biodynamic viticulture with no use of pesticides (such as herbicides and fungicides) or other synthetic chemicals. Since no animal products are used, the wines are vegan.
