Pro Tips & Common Mistakes

To achieve the best results with your Aero Press, it's important to be aware of common mistakes that can affect the final taste.

Grind Size Too Coarse

Using a grind size that is too coarse can lead to a weak and watery taste. Ensure that your coffee is ground to a medium to fine consistency.

Incorrect Water Temperature

Using water that is too hot or too cold can affect the extraction of the coffee. Aim for a water temperature of 195°F (90°C) for optimal results.

Over or Under Brewing

Brewing for too long or too short can result in an over-extracted or under-extracted taste. Aim for a brewing time of 2 to 4 minutes for a balanced cup.

Ignoring the Stir Step

Skipping the stir step can lead to uneven saturation, resulting in a more bitter and uneven taste. Always stir the coffee gently to ensure even saturation.

Pressing Too Slowly or Quickly

Pressing the plunger too slowly or too quickly can affect the extraction of the coffee. Aim for a steady and slow descent of the plunger.
