cooking bishul - What's wrong with making coffee on Shabbat?


If, on Shabbat, someone pours water from a kli shlishi (which according to all opinions I'm aware of) over coffee beans which are laying on a filter is there any problem with drinking the resulting coffee water? It doesn't seem like it would be bishul, borer, m'rakeid or nolad, so I'm not sure why it would be forbidden.




I'm not looking for psak halacha, just to understand the concept.
