(There are a good number of blends these days that will give you a very solid understanding of the general “oriental” flavor profile: McConnell’s Oriental and Oriental Square blends, Presbyterian Mixture, Rattray’s Red Rapparee, and GLPease’s Charing Cross, which, for me, is an acrid-oriental forward Balkan. “Acrid” may not sound appealing, but it’s a delicious blend.)
If the OP would like to go deep and explore individual oriental varietals, it isn’t easy going to be easy these days. I don’t know how many could be found and sampled individually. As for mixtures, though, GLPease’s Embarcadero is a Virginia/oriental blend that features Izmir. McClelland’s Frog Morton on the Town featured Basma…but we all know the costs of acquiring McClelland blends in 2023. Beyond that, I think it will take some investigating.
