I hail from Kangra, Himachal Pradesh and it is a city very well known for its tea gardens. You can find both black and green tea here. Once I travelled to Palampur another city nearby and planned to try the fresh packed green tea. It is one of the most flavoured tea one can ever think of. This product is exported to most part of the world.
