Archaeologists say they have found the world's oldest known winery in a cave in Armenia, indicating that humans were distilling grapes during the Copper Age, more than 6,000 years ago. The lead author of an article about the study published on Tuesday in the peer-reviewed Journal of Archaeological Science, Hans Barnard, said the findings included a rudimentary wine press and a clay vat surrounded by grape seeds, withered grape vines, and remains of pressed grapes, as well as potsherds and even a cup and drinking bowl. Researchers said the artefacts were discovered by Armenian, US and Irish archaeologists inside a cave complex in southern Armenia, near the border with Iran and close to a village that still makes its own wine. Co-director of the excavation and assistant director of the University of California Los Angeles's Cotsen Institute of Archaeology, Gregory Areshian, said for the first time, they have a complete archaeological picture of wine production dating back 6,100 years.
