Invented by Alan Adler in 2005, AeroPress is one of the most popular coffee-makers of the modern era. It is a manual coffee machine consisting of three parts: the brewing cylinder, a pressing piston and the coffee filter with filter holder.
If you use the AeroPress for your own brew, you should be carefull to have a fine to medium grind. Your coffee should be ground just a bit finer than for a drip brewer and coarser than Turkish Coffee. The ratio of coffee to water should be 1:16, so you can use 17g of coffee for about 27 cl of water.
• Remove the plunger and the cap from the chamber.
• Put a micro-filter inside the cap and twist the cap onto the chamber.
• Stand the chamber on a mug.
• Put ground coffee into the chamber.
• Pour heated water slowly (80° – 83°C – Do not use boiling water)
• Stir the water and coffee together with the paddle for about ten seconds.
• Wet the rubber seal and insert the plunger into the chamber. Press the plunger downward. After the plunger has moved a short distance, you will feel the air pushing back. Continue pressing gently to maintain pressure and the air will push the brew through the grounds
• Leave the plunger pushed fully in and rinse the rubber seal. Brush or wipe it to remove the coffee oils.
• Stir your brew and enjoy!
AeroPress coffee tastes better because the ground coffee is totally immersed in the hot water, resulting in fast and extensive extraction of the flavour compounds. The AeroPress method shortens brew time to 20 seconds or less, which avoids the unpleasant bitterness created by slower methods. Also, the acid level of AeroPress brew is much less than conventional methods, due to the shorter brew time.
