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

1. Place a paper filter in the AeroPress basket
   • Pro tip: Pre-rinse filter with hot water to remove paper taste
2. Preheat your AeroPress by running hot water through it
   • This helps maintain consistent brewing temperature
3. Lock the basket onto the brewing chamber
4. Place assembly on your mug or server

2. The Classic Method

1. Add freshly ground coffee (17g or 2.5 tablespoons)
   • Level the coffee bed for even extraction
2. Add 220g water (or fill to number 4 marking)
   • Water temperature: 175-185°F (80-85°C)
3. Start your timer
4. Place plunger on top to retain heat
5. At 30 seconds: remove plunger and stir gently (7-10 seconds)
6. Replace plunger and begin pressing at 45 seconds
   • Press gently with steady pressure
   • Total press time should be about 10 seconds
7. Stop at the hiss
   • This prevents bitter compounds from entering your cup

Popular Brewing Variations

The Inverted Method

Many enthusiasts prefer this alternative technique:

1. Insert plunger slightly into chamber
2. Turn AeroPress upside down
3. Add coffee and water
4. Attach filter cap after brewing
5. Flip and press

Why AeroPress Works

The AeroPress combines three brewing principles:

1. Total immersion (even extraction)
2. Paper filtration (clean cup)
3. 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

1. Store AeroPress unassembled to preserve gasket
2. Replace gasket annually for optimal pressure
3. Clean immediately after use
4. 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.

Cleaning and Maintenance

1. Push plunger to eject coffee puck
2. Rinse all parts with warm water
3. Regular deep clean with mild detergent
4. Store disassembled and dry
