What you gain in September
- ↑Rtveli (grape harvest) begins in Kakheti from mid-September; vineyard visits and harvest participation are available throughout the month — this is the most important event in Georgian agricultural and cultural life, 8,000 years in practice
- ↑Weather perfects itself: 26°C with 7.6 sunshine hours and minimal rainfall; everything the city offers is available without the July and August heat making outdoor activity uncomfortable
- ↑Prices ease meaningfully from the summer peak while the city is fully operational; September is one of the best value months relative to what's on offer
What you sacrifice
- ↓Kakheti gets crowded during Rtveli and accommodation in the wine region must be booked well ahead for harvest weekends — day-tripping from Tbilisi is the pragmatic approach
- ↓September remains a popular travel month; visitor numbers are still moderately high, particularly around the harvest festival weekends
- ↓Nights become noticeably cooler from mid-September, requiring a layer for evening terrace dining
