Some time ago I commented that one of my favorite ways to brew coffee is on a moka pot which I then aeropress to clean out the particulates. Many responded that they just put an aeropress filter on the moka pot for the same results. So, I tried it. The resulting brew is VERY different and, to me, not good at all.
It seems that the aeropress filter in the moka pot is removeding the brew by requiring more pressure to boil over. The result is a bitter brew that loses any subtlety in flavor.
If you are someone that uses the “filter in pot” method, please try brewing the cup unfiltered and then pressing it. Let me know what you think.
But it also has more to do with your ratios. If the extraction is too bitter try changing a variable and see if you get a better result. More coffee, less water, etc. that’s also how baristas and the rest of us espresso makers dial in shots.
