Simply put espresso yields around 20% extraction and so does a cup of brewed coffee, it is the volume that is different. Without 9bars+/- at 195-205f I just don't see how you can come close to 1-2oz at 20% with any other brew method.

I would be very curious to see the findings you may come up with if you experiment with cold brewing coffee. I do it in 1/2 gallon mason jars at a 4 to 1 ratio in fridge for 12 hours then pour through a filter, never found the need to spend any money on this method of brewing.

FYI:  For those not in the know, this specific topic had been beaten to death ad nauseum in the aeropress thread "Aerobie Aeropress"

I've seen lots of discussion over the years here and on other forums about whether an Aeropress can make "espresso" or not, and if not, why.

Posted May 25, 2011 link

It cannot make espresso because it is not an espresso machine.  


You are welcome...

 
I chew coffee beans with my teeth while gargling with 195 F water to enjoy coffee. What is this "coffee brewing" device you speak of?

Point 1 - EXACTLY.  You can't, yet I haven't found where anyone explains why.

Question 2 - I haven't "cold brewed" using the Aeropress.  I have made small batches of cold brewed coffee, and it tends to be not much more than 16% extraction, even after 24 hours contact time.  It also tastes a lot (using the same beans) like an Aerocano brewed according to instructions.  (I do use the Aeropress to separate out the grounds - very useful there!)

That's a 25% brew ratio (50g coffee : 200g water), fine grind (about same as Aeropress), 24 hour refrigerator contact time.  It yields a coffee that is about 6% strength, which is decent when diluted 3parts to 1.  Similar to Aeropress according to directions - nutty, smooth, low bitterness but very little "character".  Can't really tell the difference between a Kenya, Ethiopia, Guatamala or Columbia.

Cooler temperatures extract SOME of the desirable flavors, accentuates nutty flavors and those associated with lighter oils, and mutes floral character and fruit notes but ALSO mutes bitter oil extraction (if not eliminate it entirely) along with muting astringency.

I am going to stick with the answer to Why is the 9 bars of pressure. From what I have read prior to 1938 espresso was made with steam and water and was pretty awful tasting, then came the piston based machine that solved that "burnt taste".

Thanks for the info on cold brew. I use beans that the profile did not come out the way I liked or beans that are getting on the old side for making cold brew for iced coffee. I never really like iced coffee until I started to cold brew it, I do not dilute it with water I just add ice and it does it all by itself. It is win win to me, the beans would have gone in the trash otherwise.

Two words: Insufficient pressure.

Is that what you're getting at?
