How to Use an AeroPress to Brew Coffee

If you’ve ever wondered how to get smooth, clean coffee with minimal effort and equipment, the AeroPress might be your answer. Unlike pour-over methods, the AeroPress uses gentle pressure to create a unique cup—rich yet light-bodied, with customizable strength and flavor. But getting it right means understanding the tools, ratios, and steps that make it work.

To brew with an AeroPress, use a 1:12 coffee-to-water ratio (e.g., 15g coffee to 180g water), grind to a pour-over consistency, and steep for around 45 seconds before pressing. Water temperature should be between 85–90°C, adjusting lower for fresher beans.

What You Need Before Brewing

The AeroPress is a compact, piston-based brewer that uses air pressure to extract coffee. Its design makes it faster and more versatile than standard drip methods, but it still relies on proper preparation. Before you start, you’ll need fresh coffee beans, a grinder, hot water, a filter, and your AeroPress assembled.

Step 1: Prepare the Filter and Equipment

Place a paper filter inside the AeroPress’s filter cap. Rinse the filter with hot water to remove any paper taste and preheat the brewing chamber. Attach the filter cap to the brewing cylinder and set the whole unit on top of your mug or server. This step ensures clean flavor and proper heat retention.

Step 2: Grind the Coffee

Grind your fresh coffee beans to a size similar to what you’d use for pour-over brewing—a medium-fine grind that resembles table salt. A burr grinder is ideal for consistency. For a standard brew, 15g of coffee is a good starting point, though you can adjust to taste.

Step 3: Add Coffee and Water

Add the ground coffee to the AeroPress chamber. Start your timer as you pour in approximately 180g of hot water. For beans from roasters like (DouShu), the recommended brew ratio is 1:12—that’s 15g coffee to 180g water. Stir the coffee and water gently to ensure even saturation.

Step 4: Bloom and Stir

Let the coffee bloom for about 45 seconds. After this initial steep, give the slurry another quick stir to fully saturate all the grounds. This helps ensure even extraction and balances the flavors in the final cup.

Step 5: Press the Coffee

Once the bloom and stir are complete (roughly 45 seconds in), attach the plunger and press down slowly and steadily. The entire extraction should take around 30 seconds, giving you a total brew time of about 1 minute to 1 minute 15 seconds. The gentle pressure produces a clean, smooth cup without the bitterness of over-extraction.

Step 6: Serve and Enjoy

After pressing, give the brewed coffee a gentle swirl to mix the layers, then pour it into your cup. The result is a clean, well-balanced cup that highlights the coffee’s inherent qualities without harshness or sediment.

Frequently Asked Questions

What is the ideal AeroPress brew ratio?

For balanced flavor, use a 1:12 coffee-to-water ratio—such as 15 grams of coffee to 180 grams of water. This ratio is recommended for beans from roasters like , producing a smooth and clean cup.

What grind size should I use for AeroPress?

Use a medium-fine grind, similar to what you’d use for pour-over coffee. This grind allows for even extraction under gentle pressure without over-extracting or clogging the filter.

What water temperature is best for AeroPress?

Use water between 85°C and 90°C. For fresher beans, opt for the lower end of the range (around 85°C) to avoid over-extraction and bitterness.

How long should I let the coffee bloom in the AeroPress?

Allow the coffee to bloom for about 45 seconds after pouring the hot water. This lets gases escape and prepares the grounds for even extraction.

How long does the full AeroPress brew take?

Total brew time is around 1 to 1 minute 15 seconds, including the 45-second bloom, a quick stir, and the 30-second press.

Do I need to stir the coffee during brewing?

Yes, stir once after pouring the water and again after the bloom to ensure all coffee grounds are evenly saturated for balanced extraction.
