Apparently True

The Ancient Greeks had a mythological river that flowed with wine

In ancient Greek mythology, the River of Dionysus, also known as the River of Wine, flowed with wine and was said to be the favorite haunt of the god Dionysus. According to myth, the river was a tributary of the River Lethe, which was said to have healing properties. The River of Dionysus was said to have flowed through the region of Thrace in ancient Greece. Archaeological evidence suggests that the myth may have been inspired by the real-life wine trade in the region.
