Rtveli (Georgian: რთველი) is the traditional vintage (the process of picking grapes and making wine) accompanied by celebrations that mark the end of the agricultural cycle for the year.
The vintage and festivities normally take place in late September in Eastern Georgia and in mid-October in Western Georgia.
Rtveli involves almost everyone in Georgia. Wine is produced by thousands of small vineyard farmers (using primarily traditional techniques of wine-making), as well as by modern wineries.
