Answer: Tamil Nadu
Notes: Cumbum Valley, known as the "Grapes City of South India," is known for Panneer Thratchai grapes, comprising 85% of India's production. Introduced in 1832 by a French priest, these grapes thrive year-round, unlike elsewhere. Recognized for its rapid growth and early maturity, it earned a Geographical Indication tag in 2023. Cumbum Valley's grapes, rich in nutrients, are used for wine, spirits, and more. Its location in Tamil Nadu's Western Ghats adds to its allure.
