The unique Don terroir
The climate of the Don Valley which covers 460 km from Rostov in the east up to Tsimlyansk Reservoir in the west is challenging for viniculture. It is very hot and dry here in summer, and winters are so severe that the vine must be covered underground and a vegetation period is very short. The temperature difference during the day and at night in August is often up to 20 ºС.
Covered viticulture is a very laborious and expensive business which can be found only in a few regions of the world. The main obstacle for growing grapes in the Don region is severe and longlasting winter frosts because if the vine is exposed to temperatures -20ºC and below for at most two days it will die. However, the reason to grow grapes where it is cold is huge, because in extreme conditions the most interesting wines are obtained.
Fragrant and well-balanced grapes which are necessary for the production of fine wines is usually acquired in a cool climate.
