Achaia Clauss

Gustav Clauss arrived in Patras in 1854 and purchased an initial 15-acre vineyard in 1859, formally establishing the winery in 1861. The estate grew to 60 acres and became the first organized winery in Greece. Clauss first bottled Mavrodaphne commercially in 1873, naming the wine after a Greek woman named Daphne whom he had loved and lost. The Demestica table wine followed in 1880 and reached commercial bottling in 1901. Austro-Hungarian Empress Elisabeth, known as Sissi, visited the estate in 1885, inspiring what became one of Greece's earliest wine tourism concepts and lending her name to the Imperial Cellar. During World War I, the winery was confiscated as an enemy asset due to its German ownership and passed to Greek control in 1920 under Vlassis Antonopoulos. Modernization followed in 1955 under Konstantinos Antonopoulos.

The estate sits on a hillside 8 kilometers southeast of Patras, with vineyards ranging from coastal plains near sea level up to 850 meters in surrounding mountain regions. A Mediterranean climate moderated by maritime breezes from the Gulf of Patras keeps temperatures temperate through the growing season. Soils are limestone-rich, calcareous, and sandy loam with good drainage and neutral pH, conditions well suited to the indigenous varieties grown here. Grapes cultivated include Mavrodaphne, Mavri Korinthiaki, Demestiha, Muscat, Roditis, and Agiorgitiko. The winery holds a total storage capacity of approximately 7,500 tonnes.
