The Cumbum valley in India is a significant area for the cultivation of Muscat Hamburg, also known as panneer thiratchai, accounting for up to 85% of the country's production. In Tamil Nadu, approximately 90% of grapes are of the seeded Muscat Hamburg variety. Sources highlight Theni as a leading district in Tamil Nadu for this grape variety, favored by farmers for its rapid growth and early maturity, making it available in markets almost year-round. The fertile soil and water availability in the region enhance the natural flavor of the fruit, which is medium to large in size and used in high-quality wine, jam, and raisin production. In 2023, Cumbum grapes were awarded the Geographical Indication (GI) tag, enabling global export opportunities.
According to Pon Katchi Kannan, president of the Periyar Vaigai Irrigation Farmers Association and coordinator of Kaamayam Thiratchai Vivasayigal Sangam, the panneer variety is primarily cultivated in the Cumbum valley, covering around 5,000 acres across 10 villages. He notes that nearly 90% of Tamil Nadu's grape production is concentrated in the Theni district, with over 300 farmers engaged in grape cultivation. The climate and soil conditions in the area are particularly suitable for the Muscat variety, with panneer grapes being harvested throughout the year, unlike other regions in India where harvesting occurs only between January and April.
