Hi Julian,
Regarding course/classes in India - see http://indianwine.com/cs/forums/t/3682.aspx
Regarding setting up basics, join our string on http://indianwine.com/cs/forums/t/3807.aspx 'Ask Puneet - Wine Business'
Regarding the best places, this is a difficult question - India is a sub Tropical Country on the whole, and vines tend to like milder climates, although excellent wines are being made in sub tropical zones. Currently the most prodigous growth is occurring in the State of Mahrashtra, with pockets elese where.
Viticultural Experets tend to be broght in from abroad. Michelle Roland ad Dr Richard Smart are amongst the best and who have worked extensively in India - Watch out though - There fees don't come cheap.
Regarding Step by Step Tutorials - I suggest you work in an established winery for a year - and this will be the best way - Alternatively you can employ a 'flying' winemaker who charge several thousand dollars per week
Excellent Books - From Sunlight to Wine - Dr Richard Smart and Wine Science (Second Edition) - R Jackson
Marketing Specialist and Consultant - Mr Alok Chandra of Gryphon Brands would also be a step in the right direction. I have communicated with him once or twice and his knowledge of the Industry in India is extensive and thorough, and very reasonable fees
Kind Regards
Puneet
