I'm not sure why I seem to have had more trouble with the Aeropress than other people, but today it came out well and I want to share.

I ground the coffee pretty fine, at 18 on my 1zpresso JX-Pro. This is finer than I use for pourover, but not nearly as fine as I use for Turkish. I put 12 grams of coffee into the Aeropress, and slowly poured 180 grams of hot water over it. I let that sit for about 40 seconds then started pressing. I added a little more water to the pressed cup to dilute it, and it is nicely balanced. For the longest time my cups had been far too sour, but this came out tasty.

I think my problem before was too much coffee and too little water.
