i’d love to hear what you think about aeropress this time around. i have a rocking smooth recipe my wife found i can share (think i posted it somewhere up there ) with you/talk you through specifics if that would be helpful. remember the plunger is rubber so it might need a bit of conditioning for proper/optimal seal if it has been neglected for years. not sure. ours has seen plenty of use consistently so i don’t know how the aerobie rubber ages/ humidity effects etc.
try some madcap beans if you don’t mind mail order bean prices. ive never found better. we use that fellow stagg ekg kettle and the temp control is very easy/specific. however, i have not come anywhere close to being able to predict taste differences as related to temp differences. so i would say the things that are going to have the biggest dent in taste are beans/freshness, good grind just prior to brew and the method of choice for inherent profile. the aeropress is where i change temps the most to experiment, but it just usually tastes very good as a method (once i started going quite coarse in accordance with 2015 aeropress championship recipe) regardless of temp setting. my point there being that i think you have an amazing grinder so i would guess finding right beans and preferred method is going to yield most obvious pleasure results. ymmv.
a last warning is to remember with method changes that taste always feel “weird” at first, almost as if taste buds don’t catch up to reality fast enough. i don’t know how to explain exactly. so i always try to remind myself going into experimentation that it might take a few gos at something before i get it right and my mind and body are ready to go with it. that could just be my mind and body so ymmv
