- Stir gently after adding water, let it steep for around 30 seconds to 1 minute, then press down gently for about 30 seconds.
This method typically produces a smooth, rich cup of coffee.
2. Inverted Method
The inverted method flips the AeroPress upside down, allowing for more immersion and a fuller extraction.
Brewing Time: 2.5-4 minutes
This method is slightly more complex:
- Use a fine to medium grind.
- Add the coffee to the AeroPress, add water, and stir.
- Let it steep for 1-2 minutes, then carefully flip and press down for another 30 seconds.
The inverted method usually results in a more robust flavor, appealing to those who prefer a stronger coffee.
3. Cold Brew Method
The AeroPress can also be used for cold brew, creating a smooth, less acidic coffee.
Brewing Time: 12-24 hours (for steeping, but only about 5-10 minutes in the AeroPress for extraction)
For cold brew in an AeroPress:
- Use a coarse grind for the coffee and steep in a cold water solution.
- After steeping in the fridge for 12-24 hours, begin the AeroPress extraction by adding the concentrate to the AeroPress and pressing down with hot water.
This is a longer process but results in a refreshing coffee that can be enjoyed iced or diluted with water/milk.
