The advent of modern Greek winemaking can be traced to 1855 when the Greek state established a model winery in Athens. In 1858, the companies exporting currants established the first Greek wine industries in the currant-dominated areas of Patras and Cephalonia. In the 1870’s, the first large-scale winegrowers-winemakers would make their appearance in Attica (Kifissia), while large wine industries were also established in Patras (Achaia Clauss, Amvourger), Cephalonia (TUEL) and Attica (Cambas). During the same decade the first organized exports and participations in wine exhibitions and competitions would commence. Following one such competition in Athens, Professor Christomanos published the results as a guidebook to fathoming Greek wine.
