Tea, more than coffee myself. I like turkish coffee, or brewed coffee from ground beans, or espresso, can't abide that filthy instant swill though, or anything with milk in it.
And, another favourite of mine, is lemon balm tea, the bushes in my garden are doing well, and provide a good few cups of tea, regenerates pretty quickly.
Teas, I have quite a collection actually, a couple of different loose green teas, various black/oolong type teas, although my favourite have to be white teas really, or lady grey, flavoured with a handful of fresh balm, really brings out the citrusy flavor.
