About Estano Estano is the name of a vineyard and olive oil estate in Sicily. In 2022, our family, the Giesbers from Druten, acquired this estate. Under the Estano brand, we are now producing and selling wine and olive oil for the first time. However, the estate itself has a nearly 200-year history as a wine and olive oil producer. The previous owner, who was 81 years old, had no successors willing to take over, necessitating the sale. Our wine is made from the Catarratto grape, an indigenous variety introduced to Sicily by the Greeks over 2,500 years ago.
