I am a long time user of the Fellow Prismo, I probably make 60% of my cups using Onyx's 2 minute immersion recipe. I would describe myself as an insufferable coffee snob, and since I began roasting my own beans last year, I've developed a pretty sensitive palate due to all the practice with cupping. It was at a Blue Bottle Coffee shop in downtown Los Angeles—one of my first experiences drinking specialty coffee—and I had just had a cup of a fruity Ethiopia extracted with the device. It was smooth and almost creamy, slightly acidic and not at all bitter. … I had never tried anything like it before and desperately wanted to repeat the same experience at home.

I don't know and don't care - you're not going to make true espresso in the Aeropress anyway (the closest you can get is the Joepresso and it's a PITA) so better off to go with what's easiest to use. Espresso Style Crema - When used with a paper filter and a darker roast coffee, the AeroPress Flow Control Filter Cap uses the build-up of pressure to create an espresso-like crema.

For instance, if you want a 5-minute steep before plunging, you can swiftly achieve that with the Prismo. The valve doesn't open until the user presses the plunger down , allowing for a greater pressure buildup that helps create an "espresso-style crema." However, to achieve this, the coffee should be ground smaller. This new feature not only opens up a wider range of particle sizes but also provides coffee brewers with greater control over the total brew time.

Try a little more coarse than classic espresso ground. The grounds should be fluffy, but not such a fine powder that you can pinch it and cause a clump. Grounds that are too fine and clump easily can compact too much, creating excessive resistance to pressing. If you find that you aren’t able to press, don’t force it.
