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? Eddie On 12/28/06, Justin Schwarz wrote: <Snip> -- My Home Coffee Roasting Blog and Profiles for the Gene Cafehttp://southcoastcoffeeroaster.blogspot.com/
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. - Scott On 12/28/06, Justin Schwarz wrote: <Snip>

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.

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. - Scott On 12/28/06, Justin Schwarz wrote: <Snip>
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.. PeterZ Roasted today in 30 MPH winds, here in LHC <Snip>
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! - S On 12/28/06, Peter Zulkowski wrote: <Snip>
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! <Snip>

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. - S On 12/29/06, Justin Marquez wrote: <Snip>

OK, so we'll develop and market a "sabotpress", which will brew coffee in extraodinary short order . . . On 12/29/06, raymanowen wrote: <Snip>
