AeroPress Inverted Coffee Tutorial | What Coffee is Suitable for AeroPress? How is the AeroPress?

The AeroPress offers versatile brewing methods with no absolute rules — let your imagination guide you to a great cup of coffee. However you want to use it, you can. It is precisely because of the AeroPress's diverse brewing possibilities, its operability, and the controllability of coffee extraction factors that the World AeroPress Championship now exists.

AeroPress Extraction Principle

In fact, the AeroPress is not only an ingenious creative achievement but also a practical product. It combines the immersion extraction of a French press, the paper filtration of pour-over, and the rapid, pressurized extraction principle of espresso. Theoretically, coffee brewed with an AeroPress can combine the richness of espresso, the purity of pour-over, and the smoothness of French press.

Flavor Characteristics of AeroPress Coffee

Clean and smooth texture: the high-density paper filter of the AeroPress produces very clean coffee. With appropriate warm water and proper pressure, you can brew coffee with low acidity, no bitterness, yet full of flavor.

Rich flavor: complete immersion brewing maximizes and evenly extracts the coffee, preserving the complete flavor profile of the beans.

Rich body: a perfect cup in 1 minute, with actual pressing time of only 20 seconds. And because of the pressurized extraction during pressing, you can achieve a richer body than with other immersion methods.

The AeroPress is probably the simplest coffee brewing method after the French press. If you explore it deeply, you can discover many unexpected variations, making it a versatile "cure-all" solution. The AeroPress was officially launched in 2005 by the American company AEROBIE, and it received a strong response immediately thanks to its ease of use, efficiency, and delicious coffee. This entirely new brewing device was invented by Alan Adler, a mechanical engineering lecturer at Stanford University. With the holding of the World AeroPress Championship (WAC), the AeroPress has become increasingly well known.

Its structure resembles a syringe. During use, place ground coffee and hot water in its "barrel," then press down the plunger, and coffee flows through the paper filter into the container. The principle combines the immersion extraction of a French press, the paper filtration of drip (pour-over) coffee, and the rapid, pressurized extraction of espresso. Through different combinations of grind size, water temperature, pressing speed, and immersion time and rhythm, you can brew coffee with wild flavors similar to espresso, or coffee with a refreshing taste and rich layers like pour-over. This "cure-all" capability gives it unique advantages for expressing the flavor of a particular bean.

FrontStreet Coffee shares how to make a cup of AeroPress coffee using the inverted method!

You'll need to prepare: AeroPress, AeroPress dedicated paper filters (or a metal filter), 18g of freshly roasted FrontStreet Coffee Huilan beans, hot water (90°C), a pouring kettle (preferably gooseneck), a coffee cup, and a coffee grinder (recommended).

Brewing Parameters:

Grind setting: 90% pass-through rate on the #20 sieve (finer than a regular pour-over grind)

Coffee-to-water ratio: 1:11 (approximately 200ml)

Water temperature: 90°C

Extraction method: Inverted

We can pre-place two circular paper filters on the filter cap, then wet them with water so they adhere. (If you don't have circular filters, you can cut regular filters to size.)

1. Assemble the plunger and chamber, then push the plunger to about the ④ mark and invert.
2. Pour in the ground FrontStreet Coffee Huilan coffee, then add an equal amount of hot water and start timing.
3. Use the stir stick to stir the coffee grounds in the chamber for ten seconds (slow circular motion).
4. Attach the filter cap with the adhered paper filters to the chamber.
5. Then secure it onto your prepared container.
6. When the time reaches one minute, flip it over and begin pressing down to "press out" the coffee.

That's it — extraction complete! The total time is about 1 minute and 20 seconds. The inverted method is more stable than the standard method, which greatly reduces the difficulty for beginners. The FrontStreet Coffee Huilan brewed this way tastes rich and delicious, with a very full nutty aroma — excellent!

FrontStreet Coffee Recommendation

Because the AeroPress is an immersion brewer with a paper filter, it rewards beans that are sweet and low in harsh acidity. If you like a fragrant, floral-leaning cup, FrontStreet Coffee's Strawberry Candy is a great fit: this Geisha blend combines a Costa Rica honey-processed coffee with a Panama washed Geisha, and brewed by immersion it releases aromas of rose, citrus, grape, and dried blueberry, with a strawberry-fudge sweetness when paired with milk.

If you want a low-acid, full-bodied black coffee with plenty of oils, FrontStreet Coffee's PWN Golden Mandheling is the classic choice. As one of Asia's best-known specialty coffees, it is sorted three times by hand plus once by machine, and after medium-dark roasting its large beans carry rich aromas of spice, caramel, cedar, and dark chocolate — an immersion brew of it is thick and full, with a satisfying oily body.

For immersion brewing in general, FrontStreet Coffee suggests grinding to a coarse-sugar consistency (EK43s setting 10.5, or 26 on a hand grinder) — more like small gravel than fine sand. If you grind too fine, fine particles can slip through and leave sediment, though if you want more layered flavor you can grind finer and simply shorten the immersion time to avoid over-extraction. A common ratio is 1:15 (15g of coffee to 225g of water), which lands around 1.1–1.2% strength. If you have no thermometer, let boiled water rest 2–3 minutes to reach roughly 90°C; because immersion adds no stirring, you can go 1–2°C higher than a typical pour-over to make up for it. A 4-minute immersion is a good starting point, then adjust to taste.
