Fellow Prismo Attachment for AeroPress Coffee Maker - Enhance Your Manual Coffee Maker to Brew Espresso-Style and No-Drip Immersion Coffees, Reusable Metal Filter
About this deal
You should get a nice crema (should last at least 30 secs, if it doesn't maybe the coffee beans were not fresh enough or your pressing was to weak or stirring not long enough). And buying coffee all the time isn’t cheap, so espresso is not always an option. That’s where the Prismo comes in.
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. But, there are 2 secret methods of using a paper filter with the Prismo metal filter that I have tried. Disclaimer: I received the Prismo from Fellow for free in exchange for an honest review and some photographs.You can use any kind of coffee you’d like. Regardless of what coffee you use, though, we’ve found that a finer grind always works best with the AeroPress coffee maker. The pressure actuated valve stays sealed until you press down. This holds your brew in the AeroPress chamber.
This method is like method 1, with a slight difference. Secret Method 2 uses a little-known attachment for the AeroPress. Here are the standard Fellow Prismo brewing instructions with your AeroPress in the normal position (i.e., not inverted).
If you use paper, you really won’t get any crema. For that kind of good looking espresso-y thing, metal is your friend.
Crema, the layer of tan-colored foam often seen atop a fresh shot of espresso, is considered by many coffee lovers as indicative of espresso quality. This isn’t entirely true. Many factors affect crema, including how recently the coffee beans have been roasted ( 5). However, since Fellow suggests that the coffee made with the Prismo filter will have a layer of crema, I was curious to see if it would deliver.
If you’re an AeroPress enthusiast, you’re almost certainly aware of the inverted method. It was developed because when using the AeroPress, as initially designed by inventor Alan Adler, some water would start leaking through or around the paper filter even before the plunger was pushed ( 4). This led to under-extracted coffee and eliminated the possibility of long steep times. To avoid this effect and achieve a more balanced flavor profile, many baristas started setting up their AeroPress upside down – aka the inverted method. When it comes to pour over drippers, it’s well-known that the different paper filters significantly impact the final flavor of the brew.
