Coffee Brewing Guide - Aeropress

Brewing guidelines for Aeropress Coffee Maker:

The Aeropress is a popular full immersion coffee brewer that can be used for a rich 'espresso' style and or the more delicate 'filter' style. In a full immersion brewer, the coffee and the water are steeped together which makes it very consistent compared to a drip filter where the water passes through the bed of coffee. This makes it very flexible for various brewing methods but importantly, also highly repeatable.

So if your dose, grind and agitation are consistent then you only need to maintain a consistent steep time to ensure the brew (and resulting extraction yield) is consistent and appeals to your personal taste. Our preferred brew method for the Aeropress is the inverted (upside-down) method as depicted here in Stumptown's brew guide. It allows for two important benefits, you can measure your water and coffee with scales and there is no dripping during the steeping phase. Getting the water and coffee dose correct to within about 5% each is important because excursions greater than this become perceptible and that's when you'll start to realise your brew is not up to scratch.

Making a Filter Style Coffee with Aeropress

Our favourite filter roast recipe is as follows:

  1. Grind 11g to 12g fresh coffee on Porlex grind setting number 3.
  2. 200mL of water at 85 degrees Celsius.
  3. Break the crust gently with the stirrer, do not agitate.
  4. Steep for 2.5 minutes.
  5. Press for 30 seconds.

Making an Espresso Style Coffee with Aeropress

If you’ve got a nice espresso roast coffee like The Beansmtih Blend, it can be enjoyable if you brew it to be slightly less extracted but stronger, as it would in an espresso machine. What you’ll get here will not be as rich but it’ll be around twice to three times the strength of flavour as our normal Aeropress approach for light roast coffees. The reason this can be more enjoyable in this situation is because the espresso roast level is darker and therefore the most enjoyable flavours and optimum acidity will arrive at lower extraction yield levels. Our favourite espresso recipe is as follows:

  1. Grind 12-20g of fresh coffee on Porlex grind setting number 2.
  2. 100mL of  water at 85°C Degrees Celsius.
  3. Stir aggressively for 20-25 seconds.
  4. Flip and plunge for about 10-20 seconds.
  5. Dilute the brewed drink about 50-100mL of hot water to suit your taste. Be careful not to make it too weak though.
