I really like Vanilla so I ordered a fairly large bag (3.5 ounces) of this from the American Tea Room. Imitating JacquelineM I cut up a fresh Madagascar vanilla bean and allowed it to sit in the bag for about three weeks. The result is a deep, rich vanilla tea. I am certain that the flavor has been well-enhanced but also it may well have been quite strong before my addition.
Because of the strength of the vanilla, my tasting note may be a bit off. The black tea support seems to be excellent but also chosen as a backdrop to promote the vanilla.
If you like vanilla I would highly recommend JacquelineM’s method and get the best vanilla bean you can find and doctor the tea. I did not taste the tea previously, because I put the smallest hole in the bag possible to add my vanilla bean segments. It’s delightful and not the least bit ersatz!
