Agiorgitiko (; also known as Aghiorghitiko) is a red Greek wine grape variety that, as of 2012, was the most widely planted red grape variety in Greece, ahead of Xynomavro. The grape has traditionally been grown in the Nemea region of the Peloponnese but can be found throughout the country including Attikí (Attica) and Makedonía (Macedonia).
One of the more commercially important indigenous Greek varieties, it can exhibit a wide range of characteristics, from soft to very tannic, depending on factors in the growing and winemaking processes. The grape is typically made as a varietal, though it is notably blended with Cabernet Sauvignon in the area around Metsovo to make the table wine traditionally called katoi. In the region of Nemea it is often made into rosés of oak-aged red wines. The wines are known for their high level of fruitiness but tend to lack some acidity and body.
The red wine produced from the grape is characteristically spicy with notes of plum. It has low acidity but good fruitiness and coloring.
Agiorgitiko is generally planted in dry, infertile soil to encourage the production of fewer but more concentrated grapes, ripening after mid-September. because of the legend that after the Greek hero slayed the Nemean lion, it was the local Nemean wine made from Agiorgitiko that he consumed. (Some versions of the story has Hercules consuming the wine before slaying the lion.) Another legend states that the wine was a palace favorite of king Agamemnon who led the Greek forces during the Trojan War.
The name Agiorgitiko means literally "St. George's grape" which could be a reference to the chapel of Saint George in Nemea or to Saint George's Day which is celebrated in November around harvest time in some Eastern Orthodox Churches. However, in many of the Greek areas where Agiorgitiko is grown, Saint George's Day is celebrated in April or May which cast doubt on the theory that the grape's name is affiliated with the feast day. Another theory is that the grape is named after one of the many Greek towns named after the Christian saint.
New clones
For most of the 21st century, growers have been working with Greek wine authorities to produce new virus-free clones of Agiorgitiko that have the potential to resist most grape disease, including botrytis bunch rot, and produce small berries with thicker skins that could ripen to higher sugar levels with most consistent yields. In 2012, several of these new clones were released to Greek wine growers who have slowly begun replanting their Agiorgitiko vineyards. In Nemea, the grape is only used for red wine production with its use in making rosé styles of wine prohibited. Around the town of Metsovo in Epirus, the grape is often blended with Cabernet Sauvignon.
