How to Use an AeroPress: The Beginner-Friendly Coffee Maker

You’ve seen the quirky syringe-like device that makes surprisingly bold and juicy coffee—maybe in a café, online, or recommended by a friend. It’s not a French press, not quite pour-over, and definitely not espresso. But what is it, how does it work, and why are so many coffee lovers obsessed with it? Let’s break down everything you need to know about the AeroPress.

The AeroPress is a fast, flexible, and easy-to-use coffee brewer invented in 2005 by Alan Adler. It combines immersion and pressure brewing, and offers endless customization—from grind size to water temperature. Most importantly, it’s forgiving enough for beginners yet precise enough for competition-level results.

What Is an AeroPress and Who Invented It?

The AeroPress is a handheld coffee brewing device that looks like a syringe or a miniature bicycle pump. It was invented in 2005 by Alan Adler, a then 70-year-old retired engineer, lecturer at Stanford, and founder of the Aerobie toy company. Frustrated with slow, messy, or overly complicated coffee makers, Adler spent twelve years prototyping—from 1993 to 2005—before launching the AeroPress. He wanted a coffee maker that was fast, portable, and produced smooth, rich coffee without bitterness.

The final design has just three parts: a chamber (or cylinder), a plunger, and a filter cap. When assembled, it resembles a syringe. The device uses air pressure and immersion to extract coffee, and can be used two main ways: standard (or “normal”) and inverted (“reverse”).

How Does the AeroPress Work?

The AeroPress brews coffee through a combination of immersion and pressure. Hot water steeps with ground coffee, extracting flavour over time. Then, using the plunger, you apply gentle pressure to push the brewed coffee through a paper or metal microfilter into your cup. This dual approach gives you control over extraction time, strength, and body.

The two main brewing styles are:

• Standard (or ‘Normal’) Method: The AeroPress is assembled with the filter cap and placed on top of your cup. Coffee and water are added, stirred, and then plunged directly downward.
• Inverted (or ‘Reverse’) Method: The plunger is inserted first, and the chamber is turned upside down with coffee and water inside. The filter cap is added later, and the whole setup is flipped before pressing. This method offers more stability, especially for beginners.

Because you can adjust nearly every variable—grind size, water temperature, brew time, agitation, coffee-to-water ratio—the AeroPress is highly versatile. It can produce anything from a clean, light cup to a rich, espresso-like shot.

Why Is the AeroPress So Popular?

The AeroPress took off after its official launch and quickly gained a cult following. Its simplicity, portability, and consistency made it a hit among travellers, office workers, and home brewers. But the real turning point came in 2008.

Tim Wendelboe, a Norwegian specialty roaster known for pioneering Nordic light roasts, hosted the first-ever AeroPress competition in his local community with just three participants. What began as a small local event evolved into the global AeroPress Championship, now held in dozens of countries with hundreds of competitors. The competition showcases the device’s flexibility—brewers use everything from extreme grind sizes to unusual water temperatures to highlight different flavours.

Its popularity also stems from how approachable it is. Unlike espresso machines or siphon brewers, the AeroPress requires no electricity, minimal setup, and cleans up in seconds. And thanks to its compact size, it’s a favourite for camping, travel, and office use.

AeroPress Brewing Variables You Can Adjust

Here’s a rundown of the key variables you can tweak when brewing with an AeroPress:

• Water temperature: Typically between 85–96°C
• Brew ratio: Commonly 1:12 to 1:16, though wider ranges are used
• Grind size: Ranges from French press coarse to espresso-fine
• Brew time: Between 30 seconds to over 2 minutes
• Agitation: Stirring method and frequency affect extraction
• Pressure: Controlled by how quickly and firmly you press
• Brew method: Normal (upright) or reverse (inverted)

Even small changes—like stirring for 10 seconds instead of 5—can produce noticeably different cups. That flexibility is what makes the AeroPress a favourite for experimentation.

Our AeroPress Recipe: Reverse Brew with Kenyan Coffee

This method comes from FrontStreet Coffee’s brewing experiments. It uses a reverse brew technique to enhance clarity and body, particularly well-suited for bright, juicy single-origin coffees like Kenyan beans.

Bean Used: Kenya Arusha (FrontStreet Coffee selection: bright acidity, sweet citrus, and tart berry notes—similar profile to the referenced Kenya '' with little tomato acidity and juicy pear sweetness)

Parameters:

• Dose: 18g coffee
• Grind Size: 20-mesh sieve, 90% passing rate (finer than standard pour-over, close to espresso-fine)
• Brew Ratio: 1:11 (18g coffee to ~200ml water)
• Water Temperature: 90°C
• Method: Reverse (inverted)
• Total Time: Around 1 minute 20 seconds

Steps:

1. Place two round paper filters in the filter cap and rinse with hot water to pre-wet (you can cut standard filters if circular ones aren’t available).

   

2. Assemble the AeroPress with the plunger pushed down to around mark ④, then flip it upside down.
3. Add 18g of ground coffee into the chamber, then pour in 200ml of 90°C water. Start your timer.

   

4. Stir the slurry for 10 seconds using a spoon or stir stick in slow circles.

   

5. Attach the pre-wet filter cap to the top of the chamber.
6. Flip the entire AeroPress right side up over your cup or server.
7. At the 1-minute mark, begin pressing the plunger down slowly and steadily until you hear a hiss. Total brew time should be around 1 minute 20 seconds.

   

The resulting cup should have a vibrant acidity—think bright fruits—with a juicy mouthfeel and balanced sweetness. The reverse method improves stability, making it ideal for newer brewers.

Frequently Asked Questions

What is the difference between normal and reverse AeroPress brewing?

Normal brewing means assembling the AeroPress right-side up with the filter cap on the bottom and pressing directly into your cup. Reverse brewing involves inserting the plunger first, adding coffee and water while upside down, then flipping the whole unit before pressing. Reverse brewing offers better stability, especially for beginners, and can produce slightly cleaner cups.

What grind size should I use for AeroPress?

AeroPress grind size varies depending on brew method and taste preference. For immersion-style brewing, a medium to medium-fine grind (similar to table salt) is common. For the reverse method with higher extraction, a finer grind—like one that passes 90% through a 20-mesh sieve—is often used, approaching espresso fineness.

Can I use metal filters in my AeroPress?

Yes. While the standard kit includes paper filters, AeroPress also offers a metal filter that allows more oils and fine particles through, resulting in a fuller-bodied and often more intense cup. Many brewers use both depending on flavour preferences.

How long should an AeroPress brew take?

Total brew time can range from about 30 seconds to over 2 minutes. A typical range is 1 to 1 minute 30 seconds. The reverse method example here finishes in around 1 minute 20 seconds including stirring and pressing.

Is AeroPress coffee like espresso?

No, AeroPress coffee is not espresso. While it can produce a strong, concentrated brew similar in strength to espresso, it lacks the high pressure and crema that define true espresso. However, its concentrate can be used for espresso-style drinks like lattes or Americanos.
