Sangiovese is a red grape variety that is widely grown in Italy, particularly in the regions of Tuscany, Emilia-Romagna, and Umbria. It is the main component of some of Italy's most famous wines, including Chianti, Brunello di Montalcino, and Vino Nobile di Montepulciano.

Some of the key producers of Sangiovese wines include Antinori, Castello Banfi, and Frescobaldi, all of which have estates in Tuscany.

In addition to being a key component of many Italian red wines, Sangiovese is also grown in other parts of the world, including California, Argentina, and Australia. In these regions, it is often blended with other varieties to create unique, New World-style wines that showcase the grape's signature flavors and aromas.

Overall, Sangiovese is a versatile and widely-grown grape variety that is known for its distinctive flavor profile and ability to produce high-quality wines. Whether you're a fan of classic Italian reds or are looking to try something new and unique, Sangiovese is definitely a grape worth exploring.
