Cannonau is a red wine grape variety primarily grown in Sardinia, Italy. It is known for producing full-bodied wines with rich flavors of dark fruits, herbs, and spices. Cannonau wines often have a deep red color and can exhibit a range of aromas, including blackberry, plum, and hints of earthiness. The grape is believed to be related to Grenache, a variety widely cultivated in France and other regions. Cannonau has a long history in Sardinia, where it is often associated with traditional local cuisine. The wines are typically enjoyed young but can also age well, developing more complex flavors over time.
