The AeroPress has revolutionized portable coffee brewing since its invention in 2005 by Alan Adler, a Stanford University engineering instructor also known for inventing the Aerobie flying ring. This innovative device combines pressure brewing with total immersion to create a smooth, rich cup of coffee in just one minute.

Step-by-Step Brewing Guide
1. Setup Phase
- Place a paper filter in the AeroPress basket
- Pro tip: Pre-rinse filter with hot water to remove paper taste
- Preheat your AeroPress by running hot water through it
- This helps maintain consistent brewing temperature
- Lock the basket onto the brewing chamber
- Place assembly on your mug or server
2. The Classic Method
- Add freshly ground coffee (17g or 2.5 tablespoons)
- Level the coffee bed for even extraction
- Add 220g water (or fill to number 4 marking)
- Water temperature: 175-185°F (80-85°C)
- Start your timer
- Place plunger on top to retain heat
- At 30 seconds: remove plunger and stir gently (7-10 seconds)
- Replace plunger and begin pressing at 45 seconds
- Press gently with steady pressure
- Total press time should be about 10 seconds
- Stop at the hiss
- This prevents bitter compounds from entering your cup
Popular Brewing Variations
The Inverted Method
Many enthusiasts prefer this alternative technique:
- Insert plunger slightly into chamber

Why AeroPress Works
The AeroPress combines three brewing principles:
- Total immersion (even extraction)
- Paper filtration (clean cup)
- Pressure brewing (enhanced flavors)
Troubleshooting Your Brew
If Pressing Is Too Hard:
- Grind size too fine
- Pressing too fast
- Coffee packed too tightly
If Coffee Tastes Weak:
- Increase coffee amount
- Grind slightly finer
- Extend steep time
Bean Selection Tips
AeroPress works well with:
- Light to medium roasts
- Single-origin coffees
- Complex, bright flavors
- High-altitude beans
Travel Tips
- Pack filters in the chamber
- Use the bag as a breaker protector
- Consider metal filter for travel
- Pack beans separately
Expert Tips
- Store AeroPress unassembled to preserve gasket
- Replace gasket annually for optimal pressure
- Clean immediately after use
- Store press with plunger extended
FAQ
Can I make espresso with AeroPress?
While AeroPress can't generate true espresso pressure (9 bars), it creates a concentrated coffee suitable for espresso-style drinks.
Paper vs. Metal Filters?
- Paper: Cleaner cup, no sediment
- Metal: Fuller body, more oils, eco-friendly
How many times can I reuse filters?
Paper filters can be reused 2-3 times if rinsed and dried, though fresh filters provide optimal results.
Why is AeroPress coffee less acidic?
The combination of lower brewing temperature and pressure brewing reduces acid extraction while maintaining flavor.
