Quick answer: Canonau is the signature red grape of Sardinia, grown on the island for centuries and known for its thick, deeply colored skin. That skin is rich in polyphenols such as anthocyanins and resveratrol-family compounds. PressPril includes Canonau grape polyphenols to bring this Sardinian heritage into a daily capsule the brand says supports circulation.
If you ever visit Sardinia, you will find Canonau almost everywhere: in vineyards climbing rugged hills, on family tables and in the island's proudest traditions. This deep red grape is woven into Sardinian life. PressPril includes Canonau grape polyphenols as one of its two signature Sardinian ingredients. Here is what makes this grape so special.
Meet the Canonau grape
Canonau is a red grape variety that has been cultivated in Sardinia for centuries. It is closely related to the grape known elsewhere as Grenache or Garnacha, but Sardinians consider it very much their own. It thrives in the island's hot, dry summers, strong sunshine and rocky soils, especially in the mountainous eastern provinces.
The grape is known for its deep color and robust character. Those features come from its skin, which develops a rich supply of protective plant compounds as the grape ripens under the intense Mediterranean sun.
What are grape polyphenols?
Polyphenols are natural plant compounds that help plants protect themselves from sunlight, heat and other stresses. In grapes, they are concentrated mostly in the skins and seeds. Some of the best-known grape polyphenols include:
| Polyphenol group | Where it shows up |
|---|---|
| Anthocyanins | Give red grapes their deep purple and red color |
| Flavonols | Such as quercetin, found in grape skins |
| Proanthocyanidins | Found in grape seeds and skins |
| Stilbenes | Including resveratrol, found in grape skins |
These compounds act as antioxidants, helping protect cells from everyday oxidative stress. Grape polyphenols have been widely explored for their connection to vascular wellness and healthy blood flow, and you can browse that research on PubMed.
Why sun-drenched grapes matter
Plants make more protective compounds when they face more environmental stress. Sardinia's intense sunshine, dry summers and rocky hillsides give Canonau grapes plenty of reasons to build up rich skins full of polyphenols. That is part of why this variety is so highly regarded.
Canonau in Sardinian life
Sardinia is famous for its long-lived communities, particularly in inland mountain villages. Traditional daily life there included homegrown vegetables, beans, whole grain bread, sheep's milk cheese, plenty of walking and strong family and social ties. Canonau, enjoyed in moderation at shared meals, has long been part of that culture.
The lesson many people take from Sardinia is not about any single food, but about the whole lifestyle: active days, simple plant-forward meals and time with loved ones. Learn more in our post on Sardinia longevity habits.

From vineyard to capsule
Canonau vineyards are often planted as low, sturdy bush vines that cope beautifully with heat, wind and little rain. Families have tended many of these vineyards for generations, passing down know-how about pruning, harvest timing and care. The grapes are usually picked by hand in late summer and early autumn, when the skins have reached their deepest color.
A grape with a long history
Some historians believe the grape has grown on the island for a very long time, and Sardinians proudly embrace it as part of their identity. Whatever its exact origins, Canonau is today the island's most widely planted red variety and a true symbol of Sardinian hospitality.
