Topic: Aeropress method (13 msgs / 246 lines)
1) From: Justin Schwarz
I decided to try something new with my AP today.
First I immersion brewed 1 16oz cup for 4 minutes with a coarse  
grind.  I did this in my 1-cup chemex so it would be easy to pour
after the immersion brew, I poured the brewed slurry into the AP with  
a poly filter.  The polyester filter allows for some liquid to pass  
through before it stalls.  At the point the AP stalled (right when I  
had poured the last of the liquid into it) I inserted plunger and  
pressed.
I would suggest this method for anyone using poly filters with their  
AP, I am enjoying a very delicious cup of lekempti right now using  
this frenchaero method.

Justin,
How much coffee in that 16 oz?

~20g, will probably brew a bit stronger next time though closer to  
25g would probably suit my taste.

Sounds about right.
The method is certainly an alternative to Aero inversion -- whose raison
d'etre is the prevention of excessive wash-through, an extraction bane
endemic to use of poly with normal press orientation.
Well, that and oil transmission through the poly. But that's a different
point.

Just brewed a second cup and used ~25g harrar decaf using same  
method.  With both cups I made there was much less oils present in  
the cup than using invert method, probably because they float and  
invert method pushes oil through the filter in the first part of the  
press.  other than that the two methods taste very close.  A good  
alternative for those nervous about spilling hot liquids.  I think  
I'm addicted to polyester

A very recent post at
CGsuggests
an intuitive and fetching mod to the Aero which could give more
headroom for slurry, in part accommodating the inevitable bloom that can be
problematic in larger brewings in the Aero.
I have an interest, lately, in splitting a grind into two distinct grades
using a sieve of some sort. What I'm envisioning is something like Ruya's
arrangement, but with a paper topper as the "gasket" on the portafilter
basket (or similar gizmo), between the basket and the Aero tube.
I would put the coarsest grind in the basket, and the finest above paper in
the tube. I would then add water, stir to suspend the finest grind, and
press immediately.
Based on some ad hoc testing Alan Adler recently did with puck extraction, I
suspect this would yield just about ideal extraction for the finer grind, as
well as the coarser. Just how coarse the median puck grind should be, and
the immersion grind, would be a TBD issue.
If paper would work (the press not stalling on account of pure fine grind
being above the paper), then this would be a practical use of the Aero. Use
of a basket sans polyester would be an attractive simplification.
The result should be a fairly clear cup with light fines, and less than half
the oils of an inverted poly Aero using the same amount of grind. At least,
that's the theory.   :-)
I sure wish I had a portafilter basket of the perfect size.

Great idea methinks!
Then there was the 'senior member' who said that you would not get 
enough pressure with an aeropress piston.
:(  :( :(
Whilst in the midst of modification could you not contrive pushing the 
piston with some kind of lever device, like a bottle capper or:http://cgi.ebay.com/Orange-Citrus-Lemon-Manual-Fruit-Juicer-Juice-Squeezer_W0QQitemZ140068368420QQihZ004QQcategoryZ20677QQssPageNameZWDVWQQrdZ1QQcmdZViewIteman orange juice squeezer?
These show up in thrift stores for a buck or two.
Hmm, maybe an espresso machine is easier..

Not enough for espresso, true enough. But it's been established that a
single, sub-minute press with a drip grind in a confined cake can result in
overextraction.
:-)
Puck extraction just hasn't been played with very much for conventional
coffee. The Aero makes it easy to play!

I sure would love to see someone mod one of these to be used as a 
tamping device...The one that is sold for this purpose is ~ $300... Ridiculous!

I would sure be nervous about putting 9 bar (= about 130 PSIG) in the
plastic barrel of the Aeropress.

I'd be worried about the cap, myself.
Some time ago, I had fun with Gatorade bottles and dry ice.http://snipurl.com/gatoratorA year or two later, the bottles did not seal as well around the cap, and I
gave it up.
The bottles would always break on the bottom. I suspect that's by design
with these things.
Anyway, what surprised me when testing bottles in general, was that a
Gatorade bottle would hold well over 100 PSI. That probably explains why
they shot so high! Which also suggests that if one actually succeeded in
getting 9 bars in an Aero, a failure of the cap would be somewhat
catastrophic. Just imagine the animated .gif at the above link being sans
PVC tube, with an Aero instead of a Gatorade bottle, and in your kitchen.
LOL
Good grief.

OK, so we'll develop and market a "sabotpress", which will brew coffee in
extraodinary short order . . .
