If you like to experiment, try different methods of brewing - French Press or pour over are easiest. You can try single origin beans, or blends, ground or whole bean that you grind with a propeller grinder gasp.
I consider myself a coffee snob and even I buy pre ground beans sometimes because I'm a lazy old codger. Frankly I sometimes don't want to go through my coffee ritual in the morning and just want a simple, quiet, pour over to get me going.
Absolutely nobody should be knocking the way you take your coffee.
