Family owned business since 1870, when the Koutsogiannopoulos brothers wound up on Santorini island by mistake when trying to get to Syros because of strong winds. Apparently, they liked Santorini because 150 years later the descendants are still making olive oil and wine. There was a very informative museum, nestled in a 300-meter long cave 8 meters below ground, with life size dioramas of the family's history in winemaking. We also had a wine tasting.
