The Aeropress brewer is one of the most popular home (and mobile!) brewing devices among coffee obsessives. To the uninitiated its form can be a little bewildering - it is however a simple, effective, consistent and easy to clean device - everything you need! While it was initially marketed as a brewer capable of producing concentrated (faux-espresso) extractions, it is by far best utilised to produced 'filter' coffee - that is - a filtered and more dilute, black coffee. To be more concise: an Aeropress is a fancy French press (plunger)!
To get the most out of your Aeropress we have put together this brew guide. Keep in mind however the Aeropress is a device that lends itself to experimentation - this isn't the only method to get delicious coffee from one - have fun!
(For those familiar with the terms/variation: we favour the non-inverted method as it is safer and you can brew more coffee - always a good thing.)
You will need:
- An Aeropress
- Paper (or metal) filter
- Cup or serving vessel
- Water (a blog post on this topic to come!)
- Something to stir with
- Good coffee!
- Boil your water.
- Weigh and grind 14g of your chosen coffee. (Grind size is very dependant on your grinder and other variables - but we suggest starting with something similar in size to raw sugar.)
- Place your filter in the cap of your Aeropress and attach it to the base.
- Place the base on your chosen serving vessel or cup and pour a little hot water into the base - this both rinses the filter and preheats the serving vessel.
- Finish draining the base, empty the water from your vessel and place the base back on it.
- Add your ground coffee to the Aeropress base and then vigorously pour 220g of water (just off the boil) over the grounds - ensuring all grounds are wetted - while starting your timer.
- Take the assembly off the scales (to protect them) and attach the Aeropress plunger into the base - just enough to form a seal that will stop the brew water from leaving the Aeropress prematurely. (Some coffee will have dripped through already - don't stress, it isn't anything to worry about and you don't need to discard it.)
- After 1 min 30 sec remove the plunger and stir the coffee that is floating on the surface. How you stir isn't critical - but try to repeat the method the same way each time you brew.
- Replace the plunger into the base as previous.
- After another 30 sec (2 min total brew) it is time to press! The trick to an even extraction is to press gently (to minimise channelling) - attempt to finish pressing the coffee through in around another 30 sec. (You can press all the way to the end - including the trapped air - without any negative effect on the brew.)
- Invert the Aeropress and remove the cap. Empty the spent grounds and filter into the bin (or compost!) and give everything a good rinse (or if you aren't going to brew again today give it a wash with soapy water - like any other dishes).
- Give your brew a stir, let it cool for a minute and then enjoy!
- If you find the coffees are somewhat weak/sour/watery then the coffee may be under-extracted, grind finer next time.
- If you find the coffees bitter/astringent/bland the coffee may be over-extracted, grind coarser next time.
