1. Prepare the AeroPress

  • Insert a paper filter into the AeroPress filter cap. Rinse the filter with hot water to remove any paper taste and preheat the brewer. Discard the rinse water.
  • Assemble the AeroPress by placing the plunger into the main chamber just enough to create a seal, then invert the AeroPress (plunger at the bottom, chamber open at the top).

2. Measure and Grind Coffee

  • Weigh out 15-18 grams of coffee (depending on your preferred strength).
  • Grind the coffee to a medium-fine consistency, similar to table salt.

3. Boil Water

  • Heat your water to about 85-90°C.

    If you don’t have a temperature-controlled kettle, bring water to a boil and let it sit for about 30 seconds to cool slightly.

4. Add Coffee to the AeroPress

  •  Add the ground coffee to the inverted AeroPress chamber. Give it a gentle shake to level the bed of coffee.

5. Bloom

  •  Start your timer. Pour about 30 grams of water over the coffee grounds to saturate them evenly. This step is called blooming and allows the coffee to degas, leading to better extraction.
  • Stir gently to ensure all the grounds are wet. Let it sit for about 30 seconds.

6. Add Remaining Water

  • After the bloom, slowly pour the remaining water until you reach a total of 240 grams. The AeroPress should be almost full.

7. Stir and Brew

  • Stir the coffee slurry gently 2-3 times to ensure even extraction.
  • Attach the filter cap (with the rinsed filter) to the AeroPress chamber.

8. Press

  •  After the total brew time reaches about 1:30 to 2:00 minutes, carefully invert the AeroPress over your mug.
  • Begin pressing the plunger down slowly and steadily. The process should take about 20-30 seconds. Stop pressing when you hear a hissing sound.

9. Enjoy Your Coffee

  •  Remove the AeroPress and give your coffee a gentle swirl. Let it cool slightly and enjoy!

Tips for Optimization

Experiment with Ratios: Adjust the coffee-to-water ratio based on your taste preferences. More coffee or less water will yield a stronger brew.

Grind Size: The grind size greatly impacts the flavour. Too fine a grind can result in over-extraction (bitter taste), while too coarse can lead to under-extraction (sour taste).

Water Temperature: Slight adjustments in water temperature can also alter the flavour profile of your coffee. Experiment within the 85-95° range.

Consistency: Try to maintain a consistent pouring and pressing technique for more predictable results.
