How much coffee do you want to brew?
Firstly decide how much coffee you wish to brew. We recommend using a brew ratio of 17:1. This means we are using 17 parts of water per 1 part of coffee to brew with. For the aeropress we'll use 13g of dry coffee and use 220g/ml of water to brew with.
Bring about 1/2 litre of water to a boil.
Assemble the AeroPress by pushing the rubber end of the narrower vessel into the wider vessel so it sits inside, just below the number 4 mark. Residual moisture in the Aeropress can affect the seal, so make sure it’s all dry. Remove the filter cap, place your filter paper inside and set aside.
Pour some boiling water in to pre-heat the aeropress and your mug and then empty it over your filter paper cap to rinse it.
Place your aeropress on your scales and pour in your 13g of ground coffee.
Your brewing water should be between 95-99 degrees, about 30 secs of the boil is usually ideal.
Tare your scales then simply start your timer and fill your aeropress to your scales read 220g and stir your brew to evenly wet all the grounds, 5-10 stirs should do it.
When your timer reaches 2:00 give the contents 2-3 more stirs.
Screw the cap onto the AeroPress. You’re in very close proximity to seriously hot coffee here, so please be careful. Carefully flip the whole aeropress over onto your mug.
Position it atop your mug and begin applying downward pressure. If the pushing feels too easy, your grind is likely too coarse; if it’s very hard to push, chances are the grind is a bit too fine. Your coffee’s fully brewed once it begins to make a hissing sound.
Unscrew the filter cap over a bin and empty the spent grounds. A good clean with warm water is usually sufficient after each brew but if you notice any buildup or odour then best to put it through the dishwasher (the aeropress is 100% dishwasher safe) or wash with a little detergent.
If you have well roasted freshly ground coffee and good water and still experience an overpowering, dry or overly bitter cup then grind coarser. If your coffee is quite dull, flat, and lacking body, then grind finer and/or make sure your water is at least 95 degrees. The ideal grind setting for an aeropress should give a cup that has a full, round body and a good balance between sweetness and acidity.
