This is what you should really do: take a good, carefully roasted coffee. Mill the beans fresh - the whole house will smell of it! Then try different ways of brewing it: just pour boiling water over it, for example in a press pot. This is my favourite variant. There are also very good coffee machines that brew with pressure and thus eliminate bitter substances. Maybe there are cafés in your area that work like this... Coffee is great - and by the way (despite rumours to the contrary) really healthy. Enjoy it!
