Here are our AeroPress instructions.

In this article, you will learn what the AeroPress is and how to make coffee in it.

Let's get started.

What Is the AeroPress?

The AeroPress is a simple manual coffee maker. AeroPress coffee is dense compared to coffee made with drip brewing methods, but it has a clean, transparent taste.

The AeroPress is a small coffee maker and it consists of 2 main parts: an open cylinder with numbers on the side and a plunger. In principle, the AeroPress is very similar to a syringe.

Coffee is brewed in an AeroPress coffee maker as follows:

  • Ground coffee is poured into the AeroPress chamber.
  • Hot water is poured in from above.
  • The coffee is stirred to ensure all the grounds are evenly wet.
  • The plunger is inserted into the AeroPress chamber and the whole construction is placed on top of a cup.
  • The plunger is pressed down, pushing brewed coffee into the cup through the filter installed at the base of the cylinder.

The creator of the AeroPress, Alan Adler, recommends the use of paper filters, although metal filters can also be found for sale. Adler believes that paper filters help prevent cafestol, which leads to high blood cholesterol levels, from entering the finished drink.

Alan's second recommendation—to use water heated to 176°F (80°C) instead of boiling water—is contrary to intuition. However, it is at this temperature, as Alan insists, that the most delicious drink is obtained.

Still, you can deviate from this recommendation, as most AeroPress users probably do, and just add a little chilled water after the water boils. If you can use a kettle with a temperature setting, that's even better.

How to Make AeroPress Coffee

AeroPress coffee can be brewed in a variety of ways. We will not list all of them, but you can familiarize yourself with them by downloading the free iOS app AeroPress Timer or an alternative that works with Android.

There are two main AeroPress brewing methods: classic and inverted. The difference is that with the classic method, coffee starts dripping through the filter right after hot water is added, while with the inverted method, the coffee and water mix together longer, like with immersion methods.

The inverted method keeps the water in the AeroPress chamber longer for a longer extraction time. This is because coffee can't drip through the filter when the AeroPress is upside down. Some people consider this an advantage over the classic method, but this does not particularly affect the taste of the finished drink.

When brewing in an AeroPress, you can also change the grind size and the ratio of coffee grounds to water. We'll list the proportions that gave us good results, but we encourage you to experiment with these variables to find your ideal taste.

There are many AeroPress coffee recipes, and new ones emerge every year at national and world championships. There is no one correct way to brew coffee in an AeroPress.

To prepare coffee in AeroPress coffee maker using either the classic method or the inverted method, you will need the following:

  • Pure drinking water (total mineralization 70-150ppm; temperature 194-201°F/90-94°C)
  • Coffee grinder
  • Scale with timer
  • Kettle
  • AeroPress with filters and something to stir with
  • Coffee beans (ideally single- origin)
  • Cup

The average brewing time in an AeroPress is 90 seconds.

Next, let's take a look at the step-by-step instructions for first the classic method and then the inverted method:

Classic method

  1. Bring water to a boil. You'll need 7 fl oz (210 ml).
  2. Weigh out 0.5 oz (15 g) of coffee beans if you prefer weak coffee, or 0.63 oz (18 g) if you prefer stronger coffee.
  3. Grind the coffee beans. The grind size should be similar to a fine drip size—slightly smaller than sea salt.
  4. Place the paper filter in the removable plastic lid of the AeroPress.
  5. Wet the filter with hot water. This helps the filter stay fixed in the lid. Be careful; the water is hot and the lid is small. Pour the hot water slowly so it completely soaks the filter.
  6. Fix the filter cap in the AeroPress chamber and place the AeroPress on your cup. The filter should be at the bottom. Put the whole apparatus on the scale.
  7. Add the ground coffee to the AeroPress chamber.
  8. Pour 7 fl oz (210 ml) of hot water into the AeroPress chamber.
  9. Stir the coffee 3-4 times. Then insert the plunger—don't push down yet—and wait 60 seconds.
  10. Press down on the plunger. Try to take 30 seconds to press it all the way down. When you hear a hissing sound, it means there's no water left in the AeroPress and you're done brewing.
  11. Your cup of coffee is ready!

Inverted method

  1. Bring water to a boil. You'll need 7 fl oz (210 ml).
  2. Weigh out 0.5 oz (15 g) of coffee beans if you prefer weak coffee, or 0.63 oz (18 g) if you prefer stronger coffee.
  3. Grind the coffee beans. The grind size should be similar to a fine drip size—slightly smaller than sea salt.
  4. Place the paper filter in the removable plastic lid of the AeroPress.
  5. Wet the filter with hot water. This helps the filter stay fixed in the lid. Be careful; the water is hot and the lid is small. Pour the hot water slowly so it completely soaks the filter. Don't put the lid on the AeroPress yet.
  6. Make sure your AeroPress is dry.
  7. Insert the plunger partway into the AeroPress chamber. Place the AeroPress on the scale. The AeroPress should be upside down.
  8. Add the ground coffee.
  9. Bloom the coffee. To do this, use twice as much water as ground coffee. If you're using 0.5 oz (15 g) of coffee, pour in 1 fl oz (30 ml) of water. If you're using 0.63 oz (18 g) of coffee, pour in 1.2 fl oz (36 ml) of water. Keep track of the weight of the ingredients using the scale you placed the AeroPress on. The water should be heated to a temperature of about 180-205°F (82-96°C).
  10. When blooming the coffee, make sure the water soaks the grounds evenly. Tamp the grounds lightly with a spoon or spatula if necessary. Let the coffee release carbon dioxide for 30 seconds.
  11. Pour the rest of the hot water into the AeroPress chamber.
  12. After one minute, stir the coffee, then add the AeroPress lid so it fits snugly into the grooves.
  13. Turn the entire apparatus over with a quick, precise motion. Place it on your cup and push down on the plunger.
  14. Your coffee is ready!
