I’ve recently been watching James Hoffman’s AeroPress series on YouTube, and wanted to share what I’ve learnt from his experiments that I have adopted into my own process before he shares his ultimate guide to AeroPress in the coming days. I’ll share the pieces I have adopted, and then list out my own technique after it.
What I have adopted into my AeroPress technique
- Let the coffee steep for longer
Prior to learning the outcome of James’ experiments, I used to: do a bloom, let it sit for about 15 seconds, add the rest of my water, put on the cap, flip it and plunge. This probably took about 1.5 – 2 minutes and resulted in a decent cup of coffee, but after seeing that you get more extraction if you wait 30 seconds to a minute longer, I now let the coffee steep in the AeroPress for an additional minute or so after flipping the Aeropress onto my mug.
2. Let the coffee settle after flipping onto my mug
This is connected to the step above, but now I wait 30 seconds to 1 minute longer after the AeroPress has been flipped onto the mug for greater extraction time but also to let the coffee settle at the bottom. This means when that plunging, more of the water is plunged through more of the coffee, resulting in better extraction.
3. Plunge with as little force as possible
This is something that I had seen the AeroPress inventor Alan Adler talk about in an instructional video previously, but now adopt after seeing James support from his blind taste tests.
My AeroPress technique
So without further ado, here is how I currently make coffee with my AeroPress. This has evolved over time and takes tips from a bunch of different sources (to name some – 3FE brew guide, countless YouTube videos, and an old colleague’s app for iPhone Sup Coffee Timer).
- Weight out your beans. The ratio of beans to water I used is 1:14.7 (most of the time I use 17g of beans and 250g of water).
- Grind your beans (if you have a Commandante C40 grinder, I set to 16 or 17 clicks – double the clicks if using RedClix).
- Boil your water (I use water just off the boil).
- Invert your AeroPress leaving as much room in the chamber as possible (I do this when using 250g water).
- Put your ground coffee in the AeroPress.
- Add 60 – 70g of water and swirl (often called the bloom phase). James didn’t see a benefit to this in his experiments but I recommend doing it if you are adding 250g of water. I do this because if you add all of the water without blooming first then you will have a lot more bubbles when the chamber is full, and it’s harder to stir.
- Add the rest of your water and stir.
- Add your filter paper to the cup and wet it.
- Add the cap with the paper added to the AeroPress and screw on.
- Plunge any air out of the AeroPress before inverting.
- Invert the AeroPress onto your cup and wait for about a minute.
- Then, plunge with as little force as you can until all of the water is in your cup (takes about 30 seconds).
- Lift off the AeroPress and enjoy your delicious coffee!
