I enjoy several tea blends from Ahlusion. I believe he extracts the flavors from actual tea leaves. Some claim he makes the best teas in the business. I certainly agree that they are darned good.
On the flip side. Slim's ejuice, a discount vendor, has black tea on the menu and will ad any flavor to it that you wish. Most vendors don't offer straight up tea and usually blend it with a fruit, vanilla, caramel, peach, cream, etc to take away the bitterness/dryness of straight tea. That said, it only takes a small amount of fruit to overpower the more subtle flavor of tea so don't request too much of something else with your tea if there is a customization option. I ordered black tea from Slim's with just a touch of caramel and pear, at my request, and it is fantastic. Ahlusion has had that combo in their line up as well and it's very popular,though a little heavy on the pear IMO. Tastes vary so maybe you won't even like it, but I sure do and a lot of other tobacco loyal ECF members have also added teas to their rotation.
I few months ago I decided to take my fav tea leaves ( Earl Grey, strong black tea ) I did my thing with it and decided to taste it , YUCK.... Strong and gross .... I diluted it and tried it after it sat in my fridge for a few months and its wonderful. I like it straight and I like it with a suggestion of a flavor apprentice flavor called mojito ( lemon and mint ) really like it, I make it real light.
