Use less water (should go sour) and see how it tastes and then use more water (go from just right to weak).
Then, start playing with the amount of grinds. Try more and see what happens with the fixed water you like. Then go less.
Then you can play with the grind size. Lol there is a coffee compass image you can search for as well to help see what causes things, but play with the water amount first it's the easiest.
I'm not sure I'm seeing or tasting a difference with this, but I'm only grinding like 11g to 15g. Maybe if I was doing like 30g or more it would help. I do enjoy dropping the beans a few at a time in the hopper.
There is a video from Lance Hedrick for the aeropress on making old coffee taste passable. I know you can't control the grind size, but try it out if you already have the aeropress handy.
I switched to Hot Cereal ( red mill ten grain) as my regular cereal was getting so expensive that I could justify my breakfast costs. Oat Milk+Cereal =$$ While what I switched to isn't the cheapest option, it keeps me going till lunch and I just add water, honey, and calcium powder to it. 👍
I'm running a pixel 7 with out a protector, but a basic phone case. Run fine and it's going to be supported by 3rd party roms for that extra security/os longevity.
What about them ISPs?
