Georgia is one of the oldest wine-producing countries in the world. The fertile valleys and protective slopes of the South Caucasus were home to grapevine cultivation and neolithic wine production for at least 8000 years. Due to millennia of winemaking and the prominent economic role it retains in Georgia to the present day, wine and viticulture are entwined with Georgia's national identity. In 2013, UNESCO added the ancient traditional Georgian winemaking method using the Kvevri clay jars to the UNESCO Intangible Cultural Heritage Lists. The best-known Georgian wine regions are in the country's east, such as Kakheti (further divided into the micro-regions of Telavi and Kvareli) and Kartli, but also in Imereti, Racha-Lechkhumi and Kvemo Svaneti, and coastal areas like Adjara and Abkhazia. The roots of Georgian viticulture have been traced back by archeology to when people of the South Caucasus discovered that wild grape juice turned into wine when it was left buried through the winter in a shallow pit. This knowledge was nourished by experience, and from 6000 BC inhabitants of the current Georgia were cultivating grapes and burying clay vessels, kvevris, in which to store their wine ready for serving at ground temperature. When filled with the fermented juice of the harvest, the kvevris are topped with a wooden lid and then covered and sealed with earth. Some may remain entombed for up to 50 years. Due to its diverse and unique microclimate, there are about 500 grape varieties in modern Georgia.
