hmmm, well i don’t have any expert advises. i’m just constantly exploring. the beans i find to be very important and that is never a fixed thing, so flexibility with minor adjustments and familiarization with what minor adjustments are helpful is the fluency i seek.
i wonder what your coffee descriptive ideals are. do you have flavors you are after? is it possible you just prefer a different method? have you explored aeropress/v60 and of course many others? the method chosen will yield drastically different flavors so i wonder if finding your optimal profile for bean/geography/flavor/feel and also exploring the method/other methods.
my aeropress is making the best cups these days for me. but it is hard to say without a little more info from you in terms of what you’ve tried specifically and what you like specifically. i should say i am always happy to go deep in pms if it gets too geeky here and also that i have no proprietary knowledge/training just endless active seeking.
a final thought and this will come off as sacrilege likely but i can’t consistently find great beans from anyone other than a single source i’ve listed and linked to too many times. we keep on and on trying other beans/roasters but our best beans always come from the same place and that can’t be stressed enough. fine/good beans are quite easy to find all over the place and i do remain confident i will find other sources of great beans but they have been quite elusive and the beans in the end always do have such a deep (the deepest) impact on cup/flavor.
