How to Use an AeroPress: Two Brewing Methods & Troubleshooting Tips

Ever tried making coffee with an AeroPress and ended up with something too weak, too bitter, or just confusing? You’re not alone. This simple, portable brewer packs a surprising range of results—but getting consistent, clean cups takes knowing a few key steps.

To make coffee with an AeroPress, start with 17–20g of medium-ground coffee, use water at 83–90°C, and follow either a two-pour bloom-and-infusion method or a standard full-immersion approach. Both yield clean, rich results in under two minutes.

What Makes the AeroPress Unique?

The AeroPress is a favorite among coffee enthusiasts for good reason. Its design resembles a syringe and combines elements of French press immersion, pour-over filtration, and espresso-style pressure. The result? A cup that has the body of espresso, the clarity of filter coffee, and the smoothness of French press—all in one compact device.

This versatility has made it a go-to tool for home brewers and professionals alike. Unlike espresso machines or complex setups, the AeroPress is fast, portable, and forgiving, yet still capable of producing a nuanced cup.

How to Brew Coffee with an AeroPress: Step-by-Step

Here’s how to make a standard cup of coffee using the AeroPress, based on the most common method shared by experienced users:

• What you need: AeroPress, grinder, fresh coffee (17–20g), kettle, cup, filter, and hot water (83–90°C).

1. Prep Your Equipment
Assemble the AeroPress with the black rubber plunger seated inside the brewing chamber, flipped upside down so the number “4” faces up (inverted method recommended for stability).

2. Rinse the Filter
Place the paper filter inside the filter cap, then rinse it with hot water to remove any paper taste. Discard the rinse water.

3. Add Coffee Grounds
Add 17–20g of medium-ground coffee (about one AeroPress scoop, which holds roughly 14–16g, or roughly two scoops for stronger coffee). A standard coffee scoop that comes with the AeroPress is 1.5x larger than commercial ones—about 14g per level scoop.

4. Bloom the Coffee
Start your timer, then pour 50ml (about 1/4 cup) of 83–90°C water over the grounds. Let it bloom for 45 seconds to release gases—this improves extraction.

5. Stir and Add More Water
Stir the slurry three times to break up clumps and ensure even saturation. Then add another 50ml of water for a total of around 100ml (about 1/2 cup). The water level should be just above the number “2” on the chamber.

6. Attach the Filter & Brew
After 60 seconds total, screw on the filter cap with the rinsed filter. At 1 minute 45 seconds, gently turn the whole AeroPress (now sitting on your cup) 45 degrees and apply light, steady pressure for 15–30 seconds. Stop when you hear hissing—this means extraction is complete.

Using Metal Filters for Extra Crema

If you prefer a richer mouthfeel with a slight crema-like layer, try using a metal filter instead of paper. Metal filters allow more oils and fine particles through, which can enhance texture and body. Just note that the cup will be slightly less clean than with paper.

AeroPress Brewing Tips & Tricks

• Don’t use a grind finer than medium—this isn’t an espresso machine.
• The included coffee scoop is ~1.5x larger than standard ones—roughly 14g per scoop.
• For a stronger cup, use two scoops (approx. 28g) and brew with water up to the “4” mark.
• Office water heaters may not reach true 100°C, but a slightly lower temp in the 83–90°C range still works well.
• You can split the water into two pours (first 50ml, then another 50ml) for more even extraction.
• Brew into a thick, pre-warmed cup to maintain temperature and flavor.

AeroPress Cleaning Shortcuts

Cleaning is faster than you think: after brewing, remove the cap, push the coffee puck out directly into the trash or compost, and give the rubber seal a quick rinse with soap. You don’t need to wait for the parts to fully dry before reassembling.

Frequently Asked Questions

What’s the best grind size for AeroPress?

Use a medium grind—finer than drip but not as fine as espresso. Too fine can lead to over-extraction and bitterness, while too coarse may under-extract and taste weak.

What water temperature should I use?

83–90°C is ideal. That’s slightly below boiling. Avoid using water that’s freshly boiled (100°C), as it can over-extract and scorch the grounds.

How much coffee should I use?

Most brewers use 17–20g. The included AeroPress scoop holds about 14g, so one scoop is mild, and two scoops make a stronger cup.

Do I have to use the inverted method?

No, but it helps prevent drips during brewing and gives you more control, especially for beginners. The standard method works too, but may require quicker pouring.

Can I use paper or metal filters?

Both work. Paper filters give a cleaner cup; metal filters let more oils through and can create slight crema, with a fuller body and texture.

Why is my AeroPress coffee sour or bitter?

Sourness usually means under-extraction—try a finer grind, hotter water, or a longer brew time. Bitterness often means over-extraction—use a coarser grind or reduce brew time.
