Brunello refers to Brunello di Montalcino, a high-quality red wine made from Sangiovese grapes in the Montalcino region of Tuscany, Italy. Brunello is known for its robust structure, deep flavours of dark fruits, and ability to age well. The wines must be aged for at least five years (with at least two in oak barrels) before release, contributing to their complexity and longevity.
