Fellow Prismo for Aeropress
Prismo is a pressure actuated valve designed to be used with the AeroPress® Coffee Maker.
This attachment allows for a buildup of pressure to create espresso-style coffee and creates a no drip seal for a full immersion brew.
The reusable 70 micron etched filter stops sludge in its tracks and eliminates the need for paper filters.
The valve’s small aperture also fits directly over an espresso shot glass.
This does exactly what it promises, it makes a perfect coffee. It has taken my aero press to a new level, I can recommend this product.
I came across this when looking for a steel filter and figured I'd give it a try. Good decision! It doesn't drip like paper filters so the coffee percolates properly, and the added pressure extracts more flavour. Even if you making a longer "americano" style it is a big improvement.
It won't replace an espresso machine but it will make your aeropress coffee taste 25-30% better.
Doesn't fit one of my two aeropresses. Otherwise it seems to work ok so far though I'm not sure it lives up to its marketing hype.
