dude, you drink it warm in the winter, cold in the summer...spring and fall are your choice.
to warm it, i put it in a ceramic vase (which i can find abundantly out here, as they are for warming sake), put the vase in a pot if water (it should stand up fine), and heat the water...pull out the vase, wipe off the excess water, and pour it into a small ceramic cup...presto!
but, i mostly drink it cold at this point in the season...but i guess it depends on where you live.
