My love affair with vanilla tea goes back 40 years to a chance encounter (and subsequent love affair) in a long-defunct mom 'n' pop store in San Francisco. I've tried more than a dozen, searching for that Proustian Remembrance-of-Things-Past flavor. Orchid Vanilla is one of my top two (the other is only available wholesale). The flavor is strong but not overpowering. It's better with milk, but good plain. I switch blends for my morning pot of tea and, on vanilla tea days, I look forward to it and enjoy it just a little more than my other tea-loves (but don't tell them: I wouldn't want their feelings to be hurt). And hats off to the friend who gave me a six-pack of Tea Forté blends, introducing me to such gems as this, the Bombay Chai and the decadent Hazelnut Truffle.
Taste and reactions to foods vary according to the individual; so I am adding only an anecdotal comment: I have an extremely low tolerance for caffeine. One cup of coffee, even with breakfast gives me palpitations, and I'm awake for 36 hours. One "tall" S'bucks decaf gives me the shakes. Soooo, while the website quantifies the amount of caffeine in one pyramid of Orchid Vanilla as "robust" (halfway between Medium and High), my experience has been quite different. I can enjoy up to two cupfuls before lunch and suffer zero nervousness, and I get a full night's sleep that evening. For those of us who suffer caffeine intolerance, this is delightful news.
