The Alazani (, ) is a river that flows through the Caucasus. It is the main tributary of the Kura in eastern Georgia, and flows for . Part of its path forms the border between Georgia and Azerbaijan, before it meets the Kura at the Mingəçevir Reservoir.
The Alazani originates in the Greater Caucasus, south of the main ridge, in the northwestern part of the Akhmeta District. It flows initially to the south towards the town Akhmeta, then through the fruitful Alazani Valley of Kakheti towards the southeast. The Alazani is the center of the Georgian wine industry. For centuries, it was a main gateway for Persian invaders.
The Alazani dries up during the winter, but in the late spring, snow melt from the mountains swells the river enormously; this regularly causes flooding. The river is mainly used for irrigation and for drinking water. In the 1990s, Chinese investors built many small hydroelectric power plants, which use the Alazani's strong current. The river is also popular with tourists for rafting trips.
A light pollution of the river with biological substances comes from untreated sewage from the cities and other communities, as well as from the agricultural areas. In the districts of Kvareli and Lagodekhi, water quality is said to be quite bad.
Alazani serves also as the name of different Georgian wines, among them the semi-dry brands of Marani Alazani Valley and Old Tbilisi Alazani.
Alazani wine takes its name from one of Alazani River (, ), which forms part of the Georgian border with Azerbaijan in eastern Georgia, before flowing into the Kura River. As a result of the slightly warmer climate in the Alazani Valley, grapes grown there are sweeter than elsewhere in Georgia.
This wine is made from Rkatsiteli grapes (Georgian რქაწითელი; literally "red stem"). This is one of the oldest variety of grapes in Georgia, with archaeologists having unearthed examples in clay jars from the 3rd millennium BC. Recently Rkatsiteli grapes have been planted in Eastern Europe, the Finger Lakes region of New York and Australia.
It has a semi-sweet flavor with light fruit tones and a straw color that darkens as the wine ages. Alazani white wine goes well with fruit, nuts and deserts.
