Can wine quench one’s thirst?

In the middle ages wine was one of the safest drinks that substituted water. People of the medieval cities diluted suspicious water, thereby providing themselves with 2-3 liters of safe liquid per day. In our modern age – light whites, rose (till 12% alcohol), and sparkling wines may very well quench one’s thirst during the Summer. Especially if they are cooled till 8-10 degrees.
