Peet's Ancient Trees Organic Pu-erh is a decent take on pu-erh, which is easily my favorite variety of tea. It is packaged in little, individually-wrapped cakes and enclosed in an airtight, metal container.
Peet's recommends putting it in boiling water for a moment in order to rinse it and then steeping it in a rolling boil for five minutes. They then suggest that you can re-steep it once to make a total of four six-ounce servings.
Or you can do what I do: throw it in your TriniTEA for four minutes at a rolling boil and continue re-steeping pot after pot of 27 ounces at a time. Each successive pot is less earthy but Peet's recommendations are quite wasteful—I'm on my third pot today and it still tastes good (but not great).
