Ok. Thanks. It smells absolutely amazing but not (to me) in taste when brewed.
Before experimenting with anything else, find out what you like: Nobody else can do that.
That means, taking short cuts - buy pre-ground if you have to, but experiment.
Experiment with the Africans (Kenyan, Ethiopian, Rwandan and so on), the central Americans (El Salvador, Nicaragua, Costa Rica, etc), the coffees from South America (Colombia, Brazil, among others), and yes, some from Asia (such as Java). See what you like.
Do you like it strong?
Then, check which style - bold, dark roast, medium roast, you like: For example, there is French roast, and some of the really dark roasts much admired by some on this very thread.
My sense is that only when you have a rough idea of the style, and country, of coffee that you like should you seek to set about improving how you make it.
