Biondi Santi is a prestigious Italian winery, widely regarded as the birthplace of Brunello di Montalcino, one of the most famous and celebrated wines in Italy. The winery is located in the Montalcino region of Tuscany, an area known for its ideal conditions for growing the Sangiovese grape, which is the foundation of Brunello di Montalcino.

The Biondi Santi family is credited with developing the Brunello style in the late 19th century. The founder, Giovanni Biondi Santi, is said to have begun producing a distinct style of Sangiovese wine that aged longer and had a more complex profile compared to other wines in the region. His innovation led to the creation of the Brunello di Montalcino denomination in the 1960s.

The Biondi Santi wines are known for their exceptional quality, long aging potential, and distinctive character. The estate continues to produce top-tier Brunello, often seen as one of the best expressions of the Montalcino terroir. Today, the wines of Biondi Santi are highly sought after by collectors and wine enthusiasts worldwide.

Biondi Santi's iconic "Riserva" bottling, made from the best grapes of the estate, is particularly famous for its longevity, balance, and depth of flavor.
