Hi Milind,
Delhi Currently accounts for approximately 23% of The Indian Wine Market in sales. There are several avenues to entering into the wine market there.
1. Your feet - Do the hard graft yourself and contact the food and beverage mgrs at major hotels and retailers
2. Get into bed with an established Distributor
3. Get together with other local wineries to establish a greater sales budget and market force when establishing your presence in the new market
4. The Internet as a medium to sales
Each of the above has its pros and cons and I am not going to advocate one such route, or you could choose several of above
If you would like to know more about any particular avenue let me know. What is your wine called?
