I received an interesting comment/question on my last post from Alex, another tea blogger (his blog is
here):
I have to applaud your taste with regard to flavored tea. I like a lot of flavored tea, but I dislike the majority of it. I like the traditionally scented stuff (i.e. Jasmine, Osmanthus, or Rose Chinese teas) and I tend to like the types made by blending herbs with tea, especially herbs in the mint family (mints, shiso, basil, lemon balm, bergamot, etc.). I grow many plants in the mint family which I blend in teas myself. I've even been thinking of separating flavored teas into two or possibly three categories on RateTea.net...(1) blends with only herbs / fruit / flower / spices and no flavoring. (2) blends containing "natural flavors" (3) blends containing artificial flavors. Do you think this would be a worthwhile endeavour? It would be a huge amount of work, but it would allow people with the same concerns that you and I have to easily sort through things. I don't have a sense though of how many people with these concerns are out there! It bugs me, because companies like Upton, which are excellent with certain pure loose teas, also sell teas with artificial flavoring!This is yet another reason to avoid flavored teas at all costs. Your main obstacle, of course, is differentiating "natural" from "artificial." I was drinking a can of Diet Sierra Mist last night, and saw that it said on the can, "with natural flavors!!" As in, it's something to be proud of, when you can use lemon flavoring made from real lemons versus artificial lemons. Soda is all chemicals, though, and at least in my warped mind, lemon natural flavor is still compacted down and processed and still sort of... well, artificial.
The problem with tea is that you'll get a coconut flavored tea with coconut flakes, but coated or scented with artificial coconut flavoring. I would imagine that sometimes the tea manufacturers themselves even have no idea if they are using flavors derived from coconut, or if it comes from a plant in New Jersey which manufactures the hamburger flavor for McDonald's. Further, your second obstacle is getting the correct information from whatever representative

is in charge of answering your question for the tea company... they have no real obligation to tell you the truth. Tea is not really regulated in any consistent or official way; they don't have to disclose their ingredients. They'd be tempted to tell you all ingredients are natural... when it's much more expensive to derive flavors from their natural origin than manufacture them with chemicals and buy them in bulk.
As for herbal teas, I never much cared for them. I do like flavored earl greys; earl grey is already flavored with oil of bergamot, which may or may not be natural. I know that a lot of
Adagio's herbal teas are genuine herbs, because when they sent me lemongrass one time, I made
tom kha gai with it, and it tasted perfect. But much like buying processed food in a supermarket, you never quite know what you are getting. Outfits like
Serendipitea, Adagio and
Mighty Leaf probably use some legit ingredients, but I had an
apple flavored green tea from Serendipitea, and I am not stupid enough to believe that they squeezed granny smith apple juice onto the leaves. Same with any other fruit flavored teas... some of Adagio's taste particularly terrible.
I guess it's up to the individual reviewer to accept teas s/he is comfortable with: I see no problem with herbs like mint and flowers like osmanthus, but you still never quite know what their origin is. Some Moroccan style teas have definitely had added mint flavor, as you cannot possibly make a mint flavored tea so strong with just leaves (even though mint is very powerful in flavor). Some flowering teas have herbs or tasteful flowers in them, but those things always tasted terrible to me; as for me, I may indulge in some mint and ginger teas sometimes, but overall I am not into herbal teas... I will be keeping earl grey around, flavored or un-, because I love the bergamot taste.
In the end I might suggest separating or labeling your reviews of herbal, but you really can't always distinguish what the ratio of natural ingredients to artificial flavor is, and in this industry, I don't forsee people being honest, or even having much of an idea from where the flavors are derived.
