When I received my Fellow Prismo, naturally I was eager to try it out. I already love the smooth flavor the AeroPress delivers, so I was anxious to see if this little contraption could improve upon it.
Upon unboxing the Fellow Prismo, its design, albeit plastic, immediately impressed me. It’s a solid, easy-to-grip cap that screws onto the bottom of the AeroPress brew chamber. Also in the box is a reusable 150 micron etched permanent metal filter that promises to “stop sludge in its tracks”, as Fellow so boldly puts it.
To use, simply place the permanent filter inside the cap (logo facing toward you) before screwing it onto your AeroPress.
Obviously, before using, you’ll want to wash everything with warm, soapy water.
So, now that I have my new Prismo attached and some fresh coffee beans ground down to a very fine grind (number 1-2 on the OXO burr grinder are the best settings I’ve found so far), I’m ready to brew espresso style coffee
I dump 20 grams of ground coffee into the brew chamber and start the timer on my gooseneck kettle
. Now, I can reliably bloom my AeroPress coffee (40 grams of water) since the pressure actuated valve on the Prismo is going to hold all the contents
in until I press the plunger down.
30 seconds of bloom will suffice, then I fill up the AeroPress the rest of the way. Setting my kettle back on its base, I stir the slurry up for 20 seconds—looking good so far!
After 90 seconds of total brew time (I’m using a medium roast here, FWIW), I’m ready to fill my glass.
In pushing the plunger down, I immediately noticed the pressure actuated valve didn’t require as much force as I had expected
. In fact, it was quite effortless to push down—different from what I had been reading about up to this point.
After the plunger stops at the bottom, I remove the entire getup from the top of my mug, unscrew the cap with the filter, and plunge the coffee puck into the garbage (or compost bin). I then wash/rinse everything off and allow it to air dry in the bamboo AeroPress organizer (which works and looks fantastic, by the way).
Since I usually go for a regular cup of coffee, I fill my mug the rest of the way with hot water to suit my tastes. I typically use a spiraling motion similar to a pour over
, intentionally trying to “mix things up” to get some aeration in there (hey, it makes a difference in my head).
So after it’s all said and done, how does the coffee brewed with the Prismo taste?
