The Roussos winery was founded in 1836 and is the oldest of Santorini. It is located at Episkopi - Mesa Gonia. They cultivate 14 hectares of vine. Ioannis "Captain" Roussos' optimism and life style reminds of classic movie heroes. Its winery is really traditional that has taken only the necessary steps towards modernization.

Its strongest point is the sweet wines, like the Nama, that is produced like Vinsanto, with the difference that the grapes are sun dried for less than a week and mature in the oak barrel for only one year, and Mavrathiro, that is considered to be the best Roussos wine.
