How to Brew Decaf Coffee with an Aeropress

The Last Airbender; how air and pressure make obscenely good decaf coffee
 
The backstory of the AeroPress is a tale of scientific progress moving in the right direction and advancing humankind as a whole! What makes the AeroPress incredible and one of a kind? Lots of things, actually. 

The AeroPress was invented by Stanford engineer, Alan Adler, who at the time was more well known for his career as an educator and being the founder of Aerobie Inc. Aerobie Inc was his avenue to develop and sell the Aerobie flying ring. The genius engineer decided that his morning coffee needed some sciencing up and developed the Aeropress as a result. 
 
The way it works is by using pressure to both shorten brewing time and by reducing the bitterness of one's coffee. In addition, it has attained some international renown and has spawned competitions and scores of brewing styles and techniques. It can also brew up one of the finest espressos around. Let’s find out how to brew with one of these space-age contraptions, shall we?
 
What you will need:
• AeroPress
• Filtered or purified water
• Your chosen decaf coffee beans (or regular coffee beans if you'd prefer)
• Grinder
• Coffee bean scale
• Kettle
 
Step 1
Measure about 15 grams of decaf coffee beans with your scale and grind them up. Go for a medium-fine grind for the AeroPress. This way all the coffee infuses but doesn’t come out too silty.

Step 2
Boil about 200 grams of your filtered or purified water. When you pour your water, it should be about 93 degrees Celsius.

Step 3
Detach your AeroPress’s plastic cap and insert a paper filter. For best results dampen your filter and the cap with some of the water you boiled. This way the cap and filter can cling together as your press and also gets your AeroPress nice and warm so your decaf coffee comes out hot, too. 

Step 4
Put your AeroPress together. Make sure the other components are mostly dry, especially the seal on your AeroPress.
 
Step 5
Carefully pour in your decaf coffee grounds. 
 
Step 6
Time for your water, once again, be careful with your pours because of the AeroPress’ unique shape and design. Pour slowly, and for best results make sure your water is at about 93 degrees Celsius.
 
Step 7
Pour water over all your grounds for an even infusion and if need be, tamp down the grounds with a spoon or a knife. Wait for 30 seconds to let your grounds infuse. After 30 seconds pour the rest of your water into the AeroPress chamber. Finally, give the grounds and water a stir.
 
Step 8
Now, it is time to screw on your cap. Carefully flip the whole apparatus and place it atop your chosen vessel, preferably something sturdy and balanced. Now it is time to press! There’s gonna be some give as the coffee is pushed through. If pushing is too easy then your grounds may be a bit too coarse, while if the press is a real challenge then your grounds may be too fine. As you push, you will know that your tasty decaf coffee is ready as the AeroPress begins to hiss and squeeze the last of the air and water out.


Step 9
Good maintenance is the name of the game with every brewing vessel but certainly with the AeroPress. After brewing, unscrew your press, dispose of the used coffee grounds (though those can go in the compost heap or garden), and the paper filter. You can do this by just giving your press a final push.
 
The coffee of tomorrow!
 
Once you give AeroPress coffee a try, you will be in a futuristic world of coffee goodness. Big on novelty, fun, and technique, while low on the bitterness scale, the AeroPress is a true genius of the brewing world, and pairs perfectly with one of our tasty decaf coffees.
