Designation for natural vine occurrences that have evolved as species (types) and subspecies (subspecies) in the course of long evolutionary history. However, wild vines must not be confused with the vine genera known as wild wine. The species ranges are a reflection of the climate and vegetation history of the respective colonisation areas and provide information about the adaptability of the species. Where the ranges of different species overlap, viable natural hybrids have been able to develop through natural interbreeding. Based on the numerous finds of fossil seeds, wood remains and leaf imprints, it is considered proven that wild preforms of grapevines already existed at the end of the Cretaceous (Early Eocene) and in the early Quaternary (Oligocene), i.e. around 60 to 80 million years ago. The ice ages (100,000 to 10,000 years before today) pushed the wild vines native to Central Europe back into the Mediterranean region and the lowlands of the then non-existent Black Sea and into Central Asia.
