How the AeroPress Was Invented: Birth of a Coffee Favorite

If you've ever wanted a simple, fast way to make rich coffee without a machine, you're not alone. Many coffee lovers have searched for an easy-to-use brewer that delivers bold flavor without the complexity. That search led to one surprisingly small tool that changed how millions make coffee.

The AeroPress was invented in 2005 by Stanford University mechanical engineering lecturer Alan Adler, who holds over 40 patents in the U.S. and abroad. Released by his company, AEROBIE, it quickly gained attention for being easy, fast, and producing smooth, strong coffee.

What Is the AeroPress and Why Does It Matter?

The AeroPress is a handheld coffee brewing device that looks a bit like a syringe. You put ground coffee and hot water inside, then press down to push the brew through a paper filter. It combines elements of French press immersion, pour-over filtration, and espresso-style pressure—delivering coffee that’s rich like espresso, clean like filter coffee, and smooth like French press. Its versatility, speed, and ease of cleaning made it an instant hit.

How the AeroPress Works: Materials, Design & Brewing Logic

The AeroPress is made almost entirely of food-safe plastics approved by the U.S. FDA. The main cylinder and plunger are made of copolyester (PET), while parts like the filter cap and stirring paddle are polypropylene (PP). The rubber seal is a thermoplastic elastomer. Every component is built to last and safe for food contact—but be cautious of counterfeit versions that may use unsafe materials.

The design is brilliant in its simplicity: a chamber where you mix ground coffee and water, a filter at the bottom, and a plunger that pushes the brewed coffee through the filter and into your cup. Unlike espresso machines, it doesn’t need high pressure or electricity. Yet by adjusting grind size and pressing speed, you can produce a wide range of coffee styles.

How to Brew with the AeroPress: Step-by-Step

Here’s how to make a classic AeroPress coffee using the standard method:

• Place an AeroPress filter in the filter cap and rinse it with hot water to seal it against the chamber.
• Assemble the AeroPress on top of your cup, then add 17 grams (about 2 AeroPress scoops) of fine-to-medium-fine ground coffee.
• Pour in 80°C water up to the number 2 mark on the chamber (roughly 220 ml).
• Stir the coffee and water gently for about 10 seconds.
• Moisten the rubber seal, insert the plunger, and slowly press down over about 20 seconds until you hear a long hiss.
• The result is roughly one double espresso shot. Dilute with hot water to make an Americano, or add steamed milk for a latte.

Cleaning and Storing Your AeroPress

Cleaning the AeroPress takes just seconds. After brewing, remove the cap, push the coffee puck out, and rinse the parts. The used coffee grounds can even be composted. The entire device is designed to be durable, travel-friendly, and nearly unbreakable—perfect for brewing anywhere.

Global Impact and Variants

Since 2008, the World AeroPress Championship (WAC) has been held annually, celebrating creative brewing techniques using the device. In 2013, the finals were hosted in Melbourne. All official AeroPress units are manufactured in Palo Alto, California, USA. Every other production source is fake. Also, note: the only official color available is black.

Frequently Asked Questions

What grind size should I use for the AeroPress?

We recommend using a fine grind, but slightly coarser than what you’d use for espresso. This helps balance extraction time and flow rate for the best flavor.

Why is 80°C the recommended water temperature?

Extensive tasting—by both amateurs and professionals—shows 80°C produces the smoothest, richest cup. Hotter water increases bitterness and acidity, while cooler water can under-extract.

How can I heat water to exactly 80°C?

Use a thermometer to heat your water, or check if your office kettle or water dispenser maintains around that temperature. Many standard office systems hover near 80°C naturally.

Is it normal for water to drip through before pressing?

Yes, a little initial dripping is normal and won’t hurt your brew. To minimize it, use a fine grind, pour slowly, and fully wet the coffee bed right after adding water.

Why is pressing so hard or difficult?

Pushing too hard can clog the coffee bed. Press gently—about 0.5 cm at a time—and let the air pressure do the work. If it’s still too hard, try a coarser grind or pre-wet the rubber seal for a better seal.
