My favourite Earl Grey has got to be a small tin of Cream Earl Grey that I picked up my local tea shop. I had never had Earl Grey tea before then, but I bought the tea after smelling it. It is obscenely romantic and cool smelling, and you can taste the cream in it as you drink it.
While at a friend's house, I served him a cup of Cream Earl Grey, and it completely blew his mind. The next time I went to the tea shop, he came with me, and bought two 100g tins of the tea. I'd like to get him to try some other teas, such as greens and whites, but he loves his Cream Earl Grey so much that he refuses to try anything else.
This is a tea that would truly make Jean Luc Picard proud.
