 From 1908 the company specialised in production of the Mavrodaphne and Demestica wines.Clauss died shortly after, and the company passed into the hands of a German named Gudert from whom on the outbreak of World War I the Greek government confiscated the winery as an enemy alien asset.In 1920 it passed into the ownership of Vlassis Antonopoulos, and from then on, with a slight pause during the German occupation in World War II, the company developed rapidly.
