BS. If you are into coffee you can taste different beans. Ironically other than Ethiopian I don't think the origin country itself makes much difference (?) but maybe the farm does and then how it was roasted and when.

Most coffee shops I have been to (not Iran tho) you can order your espresso in 5 sec (after a queue perhaps) but if you want to pick a bean or get cold brew you can do that too.

I'm surprised Iran isn't more into Turkish style coffee though (?)
