Fellow Prismo Attachment for AeroPress Coffee Maker - Enhance Your Manual Coffee Maker to Brew Espresso-Style and No-Drip Immersion Coffees, Reusable Metal Filter

Product Information

Use with All Your Favourite Coffee-based Recipes: Use the Fellow Prismo to upgrade your favourite coffee-based recipes, including espresso-style, Americano, full immersion, cold brew, hot or iced tea, and many more! It doesn’t matter for this technique, for the AeroPess more broadly, nor for any other sort of immersion/infusion brewing. The whole point is that water does not drip through (as in percolation), so precise pouring just doesn’t matter. When I think of espresso coffee, I think of something that’s bold, punchy, and delicious—especially when turned into my favorite coffee beverage, the café mocha.

Pour slowly, and be as precise as possible. Even a couple grams at this ratio can throw off the flavor of the shot.Levy, S. (2015, March 16). First Alan Adler Invented the Aerobie.

Supercharge your AeroPress with the Fellow Prismo. The Prismo is a pressure-actuated valve which is designed to be used with the AeroPress® Coffee Maker. This attachment produces a buildup of pressure to brew coffee which has a consistency closer to espresso than the AeroPress can make on its own. Mouthfeel: Users report that the paper filters used with the Flow Control Filter Cap give a slightly cleaner taste and thinner mouthfeel than the Prismo's metal filter. This can be important for those who value a clean and light cup of coffee, especially for lighter and delicate flavors. With the Prismo you can do the same thing much more easily. Plus, you get the added advantages of a metal filter. With the experiment completed, it was time to reveal the ranking of the three coffee. The best cup was…drumroll… The Prismo’s seal keeps a right-side up AeroPress from dripping as it steeps. You can set it directly on your mug without losing a drop, then simply plunge whenever it’s time. No paranoia about bumping into a precariously inverted brew! The metal filter is travel-friendly

If you are used to making AeroPress with the inverted technique, you won’t need to rely on that with the Prismo if leaking was the primary reason. Now, you might think regular AeroPress filters do the same thing, but when you add around 1.5 bars of pressure, they become more porous. That means they let some of those bitter compounds seep into your cup, making the coffee taste not as great as it could. Petrich, I.L. (2020, April 21).

Once again, this method does produce a crema. And the results are a genuine improvement on the method 1 results. The problem is that a lot of water drips through immediately, which dilutes the brew. The easiest solution is the inverted method. The valve is the small bit of rubber with a cross incision on it that sits in the center of the custom cap. Unfortunately, the Prismo was rather underwhelming—even in comparison to the regular AeroPress method. Maybe the measurements ( 20 grams coffee: 50 ml water) in the recipe were a bit off- changing the ratio is probably worth exploring Verdict – Does the Fellow Prismo Deliver as Advertised?

Crema

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).

The Prismo attachment slightly improves the flavor of my “shots” when using the standard AeroPress method. I adore the Fellow Stagg EKG kettle and have used it daily for years. It’s beautiful, precise, and ergonomic. Espresso-Style Shots — The pressure actuated valve encourages the formation of a creamy mouthfeel and bold flavor to produce an espresso-like coffee. But what if the AeroPress wasn’t invented when those definitions were written? What if we replaced “espresso” in each of the definitions with “coffee”? If you don’t have one, then a regular mug is fine so long as its internal diameter of its opening can fit an AeroPress. (I believe I measured it to a range of 65mm-90mm, but don’t quote me on that.)

Espresso

The painful problem is in the way the AeroPress works. The delicious crema floats at the top. Then, at the end of your press, the ground coffee beans absorb the crema. With full-cup brews (Prismo or otherwise), I don’t bother preheating the AeroPress. Its plastic absorbs very little heat compared to the thermal mass of several ounces of water. Let me say right off the bat the AeroPress makes excellent coffee. Its rich, full immersion brew is one of my favourite coffee brewers, especially using the best coffee for AeroPress. This review considers only Prismo’s performance and whether it lives up to expectations. At this point you can lift the Aeropress off the scale, the no-drip seal will prevent any coffee from leaking out.
