Ice Brew Coffee with an Aeropress

There are many ways to make cold brew coffee and the simplest method is to add coarsely ground coffee into a container of water and refrigerate for 8 to 12 hours.

However, the full-immersion technique described above will often lead to a coffee brew which is heavy with bitter tones due to over-extraction.

If you are looking for a lighter, sweeter cold brew method then perhaps cold drip coffee is something to try. Usually, this technique requires a few hundred dollars of equipment which allows for precise control of water flow aiming for a drip rate between 1–2 drips per second.

We can reap most of the cold-drip benefits without the hassle of expensive equipment or fiddly drip-controls by using a great little device called an Aeropress.

The Aeropress is a great device with a large community following and it even has it’s own world championships.

We will be using the Aeropress as an ice reservoir and coffee filter, using thawing ice to provide a slow trickle of water through the coffee grind to extract the delicate floral aromas without over-extracting the bitterness found in full-immersion cold brew.

The setup includes:

  • 500mL collection container
  • Aeropress and funnel (we don’t need the plunger)
  • 2 Aeropress filter paper discs
  • 40g coarsely ground coffee
  • 2 trays of ice cubes (around 500mL of frozen water)

Assemble the parts:

  • Place one filter at the bottom of the Aeropress
  • Place Aeropress over collection container
  • Fill the Aeropress with coffee
  • Place the second filter on top
  • Insert the funnel and fill with ice

Once this contraption has been set up you can go to bed. Come back in the morning and you’ll have a jar of fresh, strong slow-drip coffee.

The brew is great to drink straight, on ice or made into ice-cubes to prevent further dilution. However this recipe is quite strong so I don’t mind some mild dilution.
