I've seen Twinings sold here in the US as well as Earl Grey (my husband likes that, but he's still more of a coffee lover).
I think the Earl Grey became more popular here in the US with "Star Trek: The Next Generation" since that's what Captain Pickard always asked the replicator for: Earl Grey, hot.
I have tried to like tea. I've tried all sorts of tea. I thought, I love peppermint, so maybe I'll like peppermint tea - nope. I don't know what it is about drinks that I don't like. I don't like coffee (not even the smell), tea, or soda pop. I will drink some juices (still not a favorite, but tolerable). My drink of choice is water. My oldest daughter is the same way.
