You can get High field green tea from Vignesh Enterprises, Coonoor, Ph- 0423 223023. I bought it from CRPF mela in Delhi last year. When you make green tea do not boil the water, just make sure it is about 80c. I gave the address just for an internet record; I am not associated with them. I liked Dilmah green tea (leaves) most; they probably stopped selling it in Delhi. Get organic tea, even better. And avoid tea bags, or crushed leaves. Get real leaves for green tea.
