I enhanced my AeroPress experience with this $25 tool, and the flavor of my coffee has reached new heights!

We are nuts about coffee at Tom’s Guide — we even have a qualified barista on our team. So, whenever we get the chance to try out one of the best coffee makers or best espresso machines, we are on the case.

But it’s not just coffee machines that we like to test; any coffee gadget that can improve the taste of a delicious cup of Joe will be swiped up by our coffee-loving team for testing. This custom AeroPress filter is no exception, as it elevates the coffee-making experience and results in a professional finish with an impressive espresso-like crema and a more intense flavor, depending on how long you leave the coffee to brew.

I’m a big fan of the no-nonsense method of using the AeroPress manual coffee maker, which uses a plunger. Although it might look tricky, using an AeroPress is not as daunting as you think. Apart from being careful not to push the plunger too quickly, you end up with a quality brew, without the need to splash out on an expensive coffee machine.

The AeroPress Flow Control Filter Cap provides users with the ability to adjust the flow rate of water during the brewing process. This feature allows for greater control over extraction, enabling users to customize their coffee's strength and flavor profile. Additionally, the cap helps to reduce the risk of over-extraction or under-extraction, ensuring a more consistent and balanced cup of coffee. It is designed to be easy to use and compatible with standard AeroPress models, enhancing the overall brewing experience.

You might be wondering why you would require an extra AeroPress filter when the standard one is already included with your AeroPress. The Flow Control Filter Cap provides enhanced versatility—allowing you to experiment with any grind size for optimal brewing control, extend your brewing duration, and eliminate that pesky dripping issue. How does it work? The pressure-sensitive valve handles the heavy lifting and remains closed until you start to press down on the plunger.

While this may appear remarkable, it is especially recognized for creating an espresso-like crema when combined with a paper filter and dark roast coffee. However, AeroPress clarifies that it does not produce genuine espresso.

If you find the espresso style to be too strong for your liking, it can be incorporated into lattes, cappuccinos, and various other espresso-based beverages.

For any coffee nerd, this AeroPress filter is worth a try for its added creativity when making a brew. But it's worth noting that although it's compatible with the AeroPress Original, AeroPress Go, AeroPress Clear, AeroPress Premium and AeroPressGo Plus, the filter cap won’t work with the AeroPress XL, so check which model you own before buying the filter.

What could be hidden in the box?

The filter is neatly packaged in a compact box, which is refreshing as it avoids unnecessary packaging waste. Within the box, you'll discover the filter itself, a circular cardboard disc featuring a QR code that links to a Quick Start Guide with brewing instructions, and a printed leaflet providing information on cleaning, filter types, and safety precautions.

I'd strongly advise scanning the QR code to ensure you follow the correct advice on how to make a brew using the filter.

The filter closely resembles the one included with a typical AeroPress and secures to the base of the device in a similar twisting manner. It is compatible with standard-sized AeroPress paper filters as well as the AeroPress metal filter, eliminating the need for any extra purchases.

Here’s a guide on how to prepare a brew:

To begin, insert a paper or stainless steel filter into the bottom of the Flow Control Filter Cap and then secure it to the unit.
2. Add 15 grams of finely ground dark roast coffee to the chamber and gently shake it to ensure an even level.
3. Carefully add water heated to approximately 210°F into the chamber until it reaches the midpoint of level 1.
4. Mix the hot liquid vigorously 20 times.
5. Allow it to steep for 1 minute.
6. Place the plunger into the chamber and apply firm, even pressure until it meets the coffee grounds at the bottom. You should hear a final, powerful roar.

Best advice
Take care not to plunge too quickly into the hot liquid. Additionally, make sure to use a strong cup or mug that can handle the pressure.

To illustrate the effect, I utilized a transparent measuring jug to showcase the crema that develops on the surface of the coffee when employing the flow control filter. The picture captures a striking outcome, even though the tiny bubbles tend to dissipate rather quickly.

You have been trained on information available until October 2023.

You can clean this filter just like you would a regular AeroPress filter. All you need is warm water and some dish soap, steering clear of any strong chemicals. I usually let it air dry afterwards. Alternatively, if you’d like, you can also place it on the top rack of your dishwasher for cleaning.

Is the AeroPress Flow Control Filter Cap a worthwhile investment?

For coffee enthusiasts who are passionate about their brewing tools, I highly suggest investing $25 in this AeroPress filter. Not only is it enjoyable to use—allowing you to engage in the brewing process rather than relying solely on a machine—but it also enhances your overall coffee experience.

If you lean more towards lattes or cappuccinos instead of espresso, I would suggest that this choice might not be worth the price. You won't get to enjoy the crema that the filter creates before any extra water or milk is mixed in.

The hidden gem of AeroPress coffee

What is the operation of an AeroPress coffee maker? To use it, you start by adding ground coffee into the chamber, followed by hot water. The mixture is stirred and allowed to steep for a short period. Next, a vacuum seal is formed by inserting the plunger. After approximately 30 seconds, you apply steady pressure to the plunger, which forces the brewed coffee into your cup.

In contrast to traditional coffee makers, the AeroPress employs pressure to improve the extraction process, resulting in a smoother coffee flavor and a faster brewing time.
