Different teas have characteristics which make them perfect for each application. I have, long ago, left the Madding Crowd picking up a box Lipton to quench my thrist or enjoy with friends.
Through my "trial and error", I now depend on two brands for my tea: Tazo and Twinings.
Tazo brews up as well for Hot as...
...Twinings does for Iced.
Try them and do your own taste tests (you can find variety boxes to try), but stay away from the Liptons. Well...Lipton's fine for the Chruch Social...
