The excavations were carried out by Boris Gasparyan of the Institute of Archaeology and Ethnography of the National Academy of Sciences of Armenia and Ron Pinhasi from University College Cork (Ireland), and were sponsored by the Gfoeller Foundation (USA) and University College Cork.
Armenian, American and Irish archaeologists fully unearthed a large, well-preserved 60-centimetre-deep (2-foot) vat, along with a 1-metre-long (3 ft 3 in) basin made of clay and covered with malvidin.
A number of drinking cups, found next to a set of ancient graves, were also excavated, suggesting that the site was used for funeral ceremonies and ritualistic practices.
The results of the biochemical analysis of the residues from the bottom of the wine-press and the storage jars carried out by Hans Barnard and his colleagues at UCLA were published in the Journal of Archaeological Science in January 2011.
[2] According to Areshian, the vintners used their feet to press the wine in the clay basin, the juice of which would then drain into the vat, where it would remain to ferment until being stored in jars.
