I also did one more this weekend - pushed a small batch of India well into near-vienna (just a hundred grams).  Beans all nice and oily, very dark and smoky.  Beautiful batch emulating the darkest of a *$s Sumatra.

Had enough for 3 cups (couple days rest) - normally extracted (inverted AP), very full flavor and smoky - a homey kind of smoky, not the burnt or scorched flavor I expected, but definitely overlaying the flavor.  Some not too unpleasant bitterness accompanied by a very nice toasted caramel/cocoa reminiscent of a s'more without the marshmallow.

Aeropress "recommended" - smoke and bitterness muted - but so was a lot of the cocoa notes.  Some varietal character, body not as thick as normal extraction.  Some touch of malt, unexpected.

This morning, cold brewed results from overnight (about 12 hours).  Yep - basic coffee with only the slightest hint of anything resembling bitter.  Lacking in complexity.  Not bad but not much different than just about any run-of-the-mill coffee.


I think that personally, I'm probably done with cold brewing coffee - the cheap engineer in me sees it as a waste of potentially extractable solids.  LOL

Thanks for doing the very detailed experimentation. Very interesting to read.

Have you tried brewing at room temperature instead of in the refrigerator? Perhaps that would extract some more of the solids since the temperature would be higher?

Thanks for the research.

I guess you dried the grounds in the oven over the aeropress filters?


Have you tried different steep times? 8 hours vs 12 hours vs 24 hours?

I have quick&dirty reproduced your research and compliment you on it. Thanks a bunch!

It inspired me to try a two stepped extraction:
First step
As described by you: 6h cold extraction of 15% fine grounds at fridge temperature (7 degC.),
separated by AeroPress.
[Use reversed extraction at your own peril ;-) The cold shrinks the seal on my plunger, causing leakage.]

Second step
Gently pull up and remove the plunger of the AeroPress, and push the puck back down, if necessary.
Re-hydrate the puck with hot water [I used water at 97 degC.] and strir it into suspension.
[Since It uses hot water, I could do this step by reversed method.]
Press this hot extract into a separate receiving vessel.
You can cool this down to the same temperature as the cold extract, or blend it while it's still hot with
(part of)  the cold extract.

This second extract contains most of the goodness the cold extraction left in, so blending it into the cold
extract compliments and enriches it.
Since it is a (visually) weaker extract it will also dilute it, though naturally less so than plain (hot) water would.
Mix and match to taste and / or stomach sensitivity. Yes, this two-step extraction makes for much fun experimenting!

Happy brewing!
