i don't know if i could explain it... my palette is nothing to be proud of. you can usually find it in most grocery stores in tea bags or loose leaf, which my mom uses in a french press. i think the most common brand is guyaki but there are lots of others. you can also get it bottled with flavors but i prefer it hot.
i drink it with nothing in it, sometimes i get flavored tea bags of it. you can serve it with milk/soymilk (which my mom does) and/or with a bit of sugar or honey as well. as long as you don't steep it in boiling water it shouldn't be very bitter; i like the taste of it plain.
