Filter Considerations

The AeroPress traditionally utilizes paper filters. However, experimentation with filter options is encouraged. For an even cleaner cup, some users opt to double up on paper filters. Remember to prioritize composting or recycling these filters whenever possible.

For a more sustainable approach, consider using a metal filter. These reusable filters minimize waste and can potentially impact the flavor profile of the coffee.

The Regular Brewing Process

  1. Pre-heating and Filter Rinsing
    Rinse the filter paper with hot water to eliminate any paper taste and preheat the brewing chamber. Discard the rinse water before proceeding. In case of metal filter this step is not necessary.
  2. Coffee and Water Addition
    Add 16.5 grams of coffee to the AeroPress. Then, pour in 250 milliliters of filtered water and stir thoroughly to ensure all grounds are saturated.
  3. Blooming Phase
    Attach the cap and allow one minute for the coffee to bloom. The brewing time commences as soon as the water makes contact with the grounds.
  4. Pressing and Extraction
    After one minute, invert the AeroPress over your mug and press down steadily for 30 seconds, until the device is empty. To prevent over-extraction, stop pressing upon hearing a hissing sound.

The Inverted Brewing Process

The inverted method is a popular technique employed to prevent under-extraction, which can sometimes occur with the traditional method.

  1. Begin by pressing the plunger down before adding coffee to the AeroPress.
  2. Create a seal and invert the device.
  3. Add coffee and water as usual, following the recommended waiting time.
