Azerbaijan has a successful wine industry that dates back to the 2nd millennium BC. Azerbaijan's long history of wine-making was rediscovered at archaeological digs of settlements in Kültəpə, Qarabağlar and Galajig. Archaeologists discovered stone fermentation and storage containers that included remnants and grape seeds dating back to the 2nd millennium BC. The Ancient Greeks were well aware of wine production in the area by at least the 7th century BC according to Herodotus. Later Strabo would comment in the 1st century BC about an Azerbaijani wine known as "Albania". Arabic historians and geographers described the extensive viticulture around Ganja and Barda that was taking place even after Islamic conquest of the area.
