I'd probably prefer it to Picard's Earl Grey tea. I've always imagined it's rather tasty, even though there's never any description of it. It's probably gross though since all Klingon food is worms and the like.

I bought a couple of bags of that a year or two ago and I didn't notice any difference in buzz, but maybe my caffeine tolerance was already well established. I rarely feel any energy boost from caffeine anymore.
