Biond-Santi is known for its traditional Montalcino Rosso and Brunello di Montalcino. The Biondi Santi family's Greppo vineyards date back to the 1800s. Clemente Santi, Giorgio Santi's nephew, was the first to develop red wines that could be aged, and his oenological procedures, which he learned through agriculture, chemistry, and science, were far ahead of his colleagues.
Biondi-Santi harvests early in the season. The wines are matured in huge oak casks after a long maceration period in steel for the plain Brunello and oak for the Riserva.
The Biondi-Santi Riserva, originally produced in 1888, was the first Brunello di Montalcino in history, and the announcement of a new vintage of Riserva at Tenuta Greppo, the Biondi-Santi main estate, is still a major occasion.
