I'm lucky my local co-op carries many delicious loose teas. I adore Rishi tea (from Milwaukee)1, particularly their Iron Goddess of Mercy Oolong, Jade Green, and Mahgreb Mint Green, as well as my own special mix2.
I've discovered that tea tastes so much better when it's brewed at the right temperature. Oolong brewed at 175° or Green at 165° is delicious. (Boiling water is the right temp for mint tea and other herbals.)( How to get the temp right without a fancy pot )
