Raise a glass to Georgia, which could now be the birthplace of wine.

The country, which straddles the fertile valleys of the south Caucasus Mountains between Europe and the Middle East, may have been home to the first humans to conquer the common grape, giving rise to chardonnay, cabernet sauvignon and thousands of other reds and whites we enjoy today.

In a study published Monday, researchers found wine residue on pottery shards from two archaeological sites in Georgia dating back to 6,000 B.C. The findings are the earliest evidence so far of wine made from the Eurasian grape, which is used in nearly all wine produced worldwide.

“Talk about aging of wine. Here we have an 8,000-year-old vintage that we’ve identified,” said Patrick McGovern, a molecular archaeologist from the University of Pennsylvania Museum of Archaeology and Anthropology and lead author of the study in the journal Proceedings of the National Academy of Sciences.
