I can't really make a proper judgement on Kashmiri Chai. The reason is simple. Chai should be made with milk. I don't have any milk. So I'm making it with water. And, frankly, I'm doing the tea a disservice.
That said, it tastes pretty darn good, even made in water. Chai is about warm spicy goodness, and this stuff has some warm spicy goodness.
But, like I said, you gotta make it with milk to really judge it, and I ain't got no milk. So I'm giving it a thumbs up, keeping in mind the limitations under which I'm working.
For a similar blast of warm spices, but in an herbal tea designed for water steeping, you can also try TeaSource's Margaret's Soother. It's good stuff.
