Groundbreaking Study Uncorks the Mysterious Origins of Winemaking and Grape Cultivation
A groundbreaking study from Yunnan Agricultural University has unveiled the ancestral roots of grape cultivation and winemaking. Collaborating with a global team, the scientists scrutinized the genetics of 2,503 domesticated and 1,022 wild grapevines. Their findings reveal that wild grapevines diverged into two primary genetic lineages approximately 200,000 years ago.
The research delineates two geographical clusters: one stretching from present-day Portugal and Spain in the west to Israel and Turkey in the east. Early farmers migrated westward from Asia, carrying domesticated grapevines and hybridizing them with indigenous species.
Muscat grapes, suitable for both eating and fermenting, likely originated in the Israel-Turkey region. These evolved over 11,000 years into the diverse wine grape varieties flourishing today in southern and western Europe.
However, tracing current grape types back to their original locations or even broader regions like western Asia is practically unfeasible. This complexity arises from extensive cross-breeding of table and wine grapes, as well as domesticated and wild variants. Once superior strains emerged, prior vines were eradicated, complicating genealogical tracking, noted lead researcher Wei Chen.
Thus, the exact origins of specific grape varieties may forever remain a mystery, the study concludes.
