Xinomavro is one of the most important and widely planted grape varietals in Greece. It is a red wine grape variety, known for its intense tannins.

Xinomavro's berries are small to medium in size, dark blue or black in colour, with thick skins and high levels of tannins. In terms of aromas and flavours, Xinomavro produces a wide range of fragrant, fruity notes such as raspberry, cherry, blackberry, and mulberry, with subtle herbal and spice notes. On the palate, it is full-bodied and acidic, with a medium-high level of alcohol and fresh, lingering tannins.

Xinomavro is mainly grown in the Naoussa region of northern Greece, as well as in parts of Macedonia and Thrace. Xinomavro is a vigorous, mid-ripening variety that is sensitive to grape diseases and requires careful pruning in order to produce high-quality wines. In the vineyard, it is usually harvested at full maturity, with the best examples being aged for a minimum of 18 months before release. In the winery, it is typically fermented in stainless steel tanks or large wooden barrels and aged for a minimum of three years before release. Xinomavro is used to produce a wide range of styles, from light, fruity, and easy-drinking reds to complex, age-worthy wines. The most notable styles are the medium-bodied reds of Naoussa and the lighter, more elegant wines of Macedonia. Xinomavro pairs well with a wide range of foods, including grilled and roasted meats, game, and aged cheeses. It is also known for its ability to pair well with a variety of cuisines, including Greek, Mediterranean, and Italian.

Xinomavro is sometimes referred to as the "king of Greek grapes" due to its prominence in the country's wine industry.
