Very much the same. Aeropress user for 10 years now. I bought a metal filter years ago and it’s still going strong - probably the best upgrade possible. Not sure if they exist still - bought it on kickstarter.

This year I finally “upgraded” and bought a Niche grinder and reverse osmosis water system with instant boiling water (Osmosis Zero). Mostly for convenience rather than taste. But still using the Aeropress.

My Aeropress recipe is taken from some champion winning recipe and I’ve used it for years:

  - Inverted Aeropress
  - Fill with boiling water to heat it up
  - Grind one scoop of beans (18g)
  - Pour hot water from Aeropress into mug to warm mug
  - Put grind into Aeropress
  - Pour a small amount of boiling water in and stir to wet grind
  - Start 2 min timer at same time as pouring in
  - At 1:40 fill up Aeropress rest of way, put on filter and cap
  - Let sit to 0:50 and pour out mug while waiting
  - Invert Aeropress and put on mug
  - Slowly press out coffee over the last 50s
  - Done!

The only thing you need to adjust is the grind. If too astringent, use a coarser grind. If too weak, use a finer grind. Then enjoy :).

I recently bought the Fellow Prismo AeroPress Attachment [1] which is a metal filter and a new valve head which makes any inverted brewing method simpler and, to my taste, gives a more espresso-like result.

After having an inverted AeroPress explode on me in a hotel one time, I bought a Prismo for it and never looked back.

Oh awesome, I might need to buy one of these.

You also don't have to bother with inverting with this metal filter.

Why steep the grind in a small amount of water for 2mins vs simply filling the press up straight away?

20s gives time to pour hot water and stir. It makes sense when you do it. Start the timer before pouring the first water. Idea is to wet all the grinds - if you fill it right away there may be some dry grinds on the bottom (especially with a finer grind).

I’m sure there’s a million more specific changes to the chemistry of coffee by blooming, but the basics are:

Regular coffee you bloom so channels don’t form for all the water to run down.

With the Aeropress, the coffee foams and could foam over if you fill it, so blooming first let’s you stir the bubbles out and then top it off.

The number of times that I've watched the bloom encroaching over the top of it and then carefully prodding it to release some gas so it can drop down again. I need to be more patient, I think.

are you filling it to the top with water right away?
