Tea. Earl Grey. Hot.
I've also recently got into Lapsang Souchong. It's smoked, so it has the most unique taste and aroma. It reminds me of going camping.
Genmaicha is quite nice too. It's green tea mixed with roasted rice.
As for the herbal varieties, I love roiboos, chamomile, mint, and this blend made from toasted almonds, which turns the water pink as it steeps.
