New flavors of tea is good one change and new experience. But in routine every tea lover likes their permanent flavor. I am example, in routine I like only one brand of tea leave and don;t like to change it,

Although I stick to one brand of tea , I like to collect different kinds of tea. I have different varieties of herbal teas, green tea and white teas..green tea in combination with tulsi,lemon and honey is very refreshing and delicious ..

The venture is risky but the spirit is laudable

I prefer the hot tea that contains only tea leaves, sugar and milk. However it is okay to take once any type of preparation. Unless you taste once, you can't form an opinion. Recently, I sipped tea Swami Ramdev brand (Patanjali) but this tasted and looked more like pure milk rather than tea. 

Swami has left yoga and become a food supplier. Now he is also supplying tea. It id very difficult to change one'tea taste.

Risky, no doubt. But these IITians, left lucrative jobs and ventured to make a living out of Tea selling in India. because, they were convinced  that their decision will be a hit.
