Monolithos is produced by a parent company called Bairaktris.

Bairaktaris is located in the largest winemaking region of Greece, Nemea, which has a PDO status thanks to the polydynamic and most planted red grape of Greece Agiorgitiko. This is a small, family run winery, practicing sustainable agriculture, with no use of chemicals. At least 80% of grapes come from the 15 ha of estate owned vineyards, most at 850m altitudes.
