FITS ALL AEROPRESS COFFEE MAKERS - Compatible with AeroPress Original and AeroPress Go coffee makers Interchangeable Filters - The Aeropress Flow Control Filter Cap can be used with the AeroPress Stainless Steel Reusable Filter or AeroPress Paper Micro-Filters Personally, I favor clarity (so that means paper filtration), but if you like something else, then by all means go ahead. ESPRESSO-STYLE CREMA - When used with a paper filter and dark roast coffee, the AeroPress Flow Control Filter Cap uses a build up of pressure to create an espresso like crema.

The flavor effect can be significant. Higher turbidity typically results in a heavier, more full-bodied coffee. This can be desirable for some coffee drinkers, particularly those who enjoy darker roasts or more robust flavors. COMPLETE BREW CONTROL - Attach the AeroPress Flow Control Filter Cap to your AeroPress Original, AeroPress Go or AeroPress Clear coffee maker to stop drip through which allows you to extend brew time and use coarser-ground coffee like pre-ground medium. The cap promises espresso-like crema if you use finely ground coffee, but you can also experiment with coarser-ground coffee and use long steeping times, similar as to what many coffee geeks do with the Prismo. I ended the morning already overloaded with caffeine, ready to do more experiments in the coming days, but already extremely satisfied with the new Flow Control Filter Cap. I finally managed to extract espresso-like coffee with the AeroPress! But I also managed to improve on the classic AeroPress experience. Our Flow Control Filter Cap is a game-changer for anyone who has ever used an AeroPress coffee maker," says CEO Gerard Meyer. "Users can now experiment with different grind sizes and build up pressure for that coveted espresso-style crema."

This is a significant development as it allows the brewer to be one step closer to achieving espresso-style brewed coffee just like the Fellow Prismo. It would be interesting to see if this can make a better espresso compared to other pressurized caps available for Aeropress. AeroPress' patent-pending Flow Control Filter Cap uses a pressure-actuated valve to eliminate drip through and maximize control over the coffee brewing process.

There are a few different brands out there. Some have a bit more pedigree, for instance, Able and Cafe Concetto. Simply attach the AeroPress Flow Control Filter Cap to any AeroPress coffee makers to stop drip through. For instance, this allows you to have a longer brew time and use coarser-ground coffee like all of our pre-ground medium grind coffee. This innovative accessory uses a pressure-actuated valve to eliminate drip through and maximize control over the brew process. Unlike others, this cap fits perfectly on all AeroPress coffee makers, including the new AeroPress Clear, and can be used with metal and paper filters – together or separately. Now you can make espresso-like crema and experiment with coarser-ground coffee. You probably already know and have used the regular AeroPress filters, so I won’t spend too much time on them in this post.However, the good thing about the Prismo is that it can restrict flow during the steeping phase. Therefore, when using it, you will not have any bypass or premature dripping. It's interesting to note that despite the Fellow Prismo being on the market for over five years, Aeropress has only just introduced this new filter cap. However, it is designed to fit perfectly with the Aeropress, unlike the Prismo, which can be challenging to screw on properly in my experience. After a minute and 30 seconds, it was time for a small spin. Thirty seconds later (2 minutes total), I started pressing. I noted that the pressing was similar between the two devices. The valve added some resistance, but the pressing went smoothly, perhaps because the coffee was ground quite coarsely. 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.
