when i am out, i generally prefer earl grey, and sometimes "sulaimani chai", which is lemon tea with a twig of mint leaves and some cardamom, though some makers go without the last two... sulaimani is good after some heavy meal like biryani.
i once had kashmir kahwa, though from some pakistani kashmiri members here it turned out that there are more than one of kashmiri teas.
for home, i used to bring boxes of earl grey of two companies - ty-phoo and twinings... there are a few other variations i try from these companies.
there is a dedicated thread here which you should contribute to (
Camelia Sinesis: Tea, chai, お茶、紅茶、粗茶, GITT )... the thread needs updation... please add and tag me there.
i don't have a quora account and i suppose one has to be signed-in to see the answers.
