Are you a fan of espresso, cold brew, aeropress? Do you try new beans and roasters regularly, or stay with what you know and love?
I generally prefer filter coffee (with a re-usable filter, no oil sucking paper!) or plunger, but currently have only the plunger because of lack of space. A good syphon can also be supurb. I’ve also started roasting my own beans - I’m definitely a long way from expert, but am getting pretty solid results and am am slowly improving.
Water temperature, extraction time, and grind size are the main variables dictating coffee taste. Aeropresses are so handy because you can easily control water temperature and extraction time. Get a burr grinder (not the blade grinder) to play with grind size. I have spent a lot of time playing with these three factors alone.
