I wont say that Tata tea Agni is bad but its not good as well. I am from Assam and I have been seeing Assam tea products from the childhood.
What I feel that TATA TEA Agni has the product manufactured at the last flush season that is during OCT to DEC mid. The look of the powder is itself Brownish and the there is no aroma.
It sells as it has the brand tag.
There are other better products in the market than this.
