Some students from Welingkar did make a project on new product launch in the tea category.
Your marketing communication and strategy should be in line with the vision of the company. So if you are targeting SEC A segment then you need to premium price the product and make sure that you hit the right buttons with your marketing communication and packaging.
Opening tea centre's like cafe coffee day can be one option to bring people together to try variants if you plan to introduce many.
Tea is basically perceived to be a source of refreshment so your marketing communication should work around that theme unlike the " Jagoo Re " which is a good social initiative but does nothing for the TATA TEA brand.
Feel free to get back incase you need more help
