Tea-wise, it's jasmine all the way. I find it a wonderful mid-afternoon de-stresser. I drank loads of it in a Chinese restaurant in Bristol last year, and something went "click" in my taste buds. It's been a major part of my beverage intake ever since.
Coffee? I'm on a bit of an Union Coffee Roasters kick right now. I find their coffee to have a flavour a notch above that of most ground coffees, and it's really perking up my work days right now.
