Le Chiuse is a highly regarded, family-run organic winery in Montalcino, Italy, with deep historical ties to the Biondi-Santi family and the origin of Brunello. Located on the north-northeast slopes of the Montalcino hill, it produces traditional, elegant, and long-lived Brunello di Montalcino, including a notable Riserva, using Sangiovese Grosso from high-altitude vineyards.
