Biondi Santi Tenuta il Greppo is in Montalcino. It traces its history to the 18th century, when the Biondi Santi family combined several inherited estates and sent their sons to university to study agriculture and science. By the late 19th century the family led the movement to create the Brunello di Montalcino appellation. The 62-acre estate is still in the Biondi Santi family and their Brunello di Montalcinos win high praise from reviewers. Gambero Rosso rates Biondi Santi's Brunellos at 3 glasses, the highest possible rating, nearly every vintage.
