Try a lot of sorts, and try some mixes. Earl Grey has a special aroma, - as a different one, try redbush tea. (Roibos).
Try Ceylon, China, Melroses, and then try the mixtures, - Ceylon actually makes a strong mix with earl Grey etc. Some don't mix at all, and quality is different between brands.
Ceylon is really my sort, but redbush with vanilla flavour is also quite nice.
And you're not yet into green tea or ice tea....lots of exploring to do.
