Which red grape variety is considered the most prominent in Greece?

Xinomavro is widely recognized as the most prominent red grape variety in Greece, celebrated for its versatility and ability to produce a wide range of wine styles, from fresh and fruity to complex and age-worthy. It thrives particularly well in the Northern regions of Greece, such as Naoussa and central Macedonia, where the climate and terroir contribute to its characteristic flavors of dark fruit, tomato, olives, and herbs, as well as its notable acidity and tannin structure.

While Cabernet Sauvignon, Pinot Noir, and Merlot are renowned international grape varieties, they are not indigenous to Greece and do not have the same cultural and regional significance. Xinomavro, with its deep-rooted tradition and expression of the local terroir, stands out as a true representative of Greek viticulture, making it the correct answer in this context.
