Brewing History: The Original AeroPress Technique by Alan Adler

While the World AeroPress Championship showcases thousands of complex recipes, the original method designed by inventor Alan Adler remains a masterclass in efficiency. This guide strips away the modern obsession with complicated variables to focus on the foundational physics of the AeroPress. By following this legacy technique, you achieve a clean, rich cup in under sixty seconds.

Tools and Materials Needed

To execute this method with precision, gather the following essentials:

• AeroPress (Chamber, plunger, and filter cap)
• Paper Filter
• Coffee Beans: Ground to a fine, espresso-like consistency
• Water: Heated to exactly 80%C for medium roasts or 85%C for light roasts
• The Scoop: The standard AeroPress measuring tool
• Stirrer and Timer

Step-by-Step Instructions

1. Prep the Filter: Place a paper filter in the cap. Although the original instructions skip this, always rinse the filter with hot water to remove any papery taste and preheat the vessel.
2. Measure and Grind: Dose one level scoop of coffee—approximately 15 grams. Grind this to a fine texture, much smaller than your typical drip setting.
3. Charge the Chamber: Secure the cap and place the AeroPress in the traditional upright position over a sturdy mug. Add the coffee and shake it gently to level the bed.
4. Add Water: Pour hot water slowly until it reaches the "1" mark on the chamber wall (roughly 85–90 grams).
5. Agitate: Stir the slurry for 10 seconds. This ensures every particle is fully saturated.
6. The Plunge: Insert the plunger. Instead of forcing it, rest the weight of your hands on top. Let gravity and gentle pressure do the work for 20 to 60 seconds.
7. Dilute: You now have a concentrated brew. Add hot water to the cup until it reaches your preferred strength.

Tips and Troubleshooting

If the plunger is too difficult to push, your grind is likely too fine; if it drops instantly, go finer. Temperature is your primary lever for flavor control—never use boiling water, as it scorches the delicate oils. This method yields a concentrated "puck" of grounds that should pop out cleanly into the bin, leaving the rubber seal virtually spotless.

The Expected Outcome

This technique produces a remarkably smooth, low-acidity coffee that highlights the inherent sweetness of the bean. By treating the initial brew as a concentrate, you gain total control over the final body and intensity of your drink.
