Tamil Nadu
Tamil Nadu, one of India’s southern-most states, borders on Andhra Pradesh and Karnataka in the north, Kerala in the west, and the Bay of Bengal in the east, enjoying a long coastline. There is just the one wine region, the Cumbum Valley region in the south-west corner of the state, a relatively low-lying area with an average altitude of only 400 metres. It is surrounded by the Thekkadi Hills in the west, the Varusanadu Hills in the east and the Kodaikanai Hills in the north, their peaks easily reaching to a thousand metres above sea level.

The river Vairavanar cuts through the valley and is responsible for the fertile black and sandy alluvial soils. Red loam and sand, however, dominate the valley floor with some lateritic and black soils in places.

The
region’s peculiarity is that despite being classified as mild tropical,
temperatures do not drop below 20˚ C, and in the daytime reach around 30˚ C,
right through the year. Table 1 shows the climatic data for Madurai, the
closest meteorological observation point. Cumbum Valley receives similar
quantities of rain, but it is more evenly distributed through the year, with
not a single month truly dry.
