Scott Rao has today announced a new, automated way to make filter coffee, by using the Decent Espresso Machine:

This new profile is now in the nightly de1app, or you can download it from this post, and put it on your Android tablet, in the /sdcard/de1plus/profiles/ directory.

The profile is described like this in the de1app:

A new technique developed by Scott Rao, for making filter coffee with an espresso machine and 24g basket.  The process: (1) insert two micron 55mm paper filter into the bottom of a clean portafilter basket.  (2) Rinser the filter and basket with hot water.  (3) Fill the basket with 20g to 22g of finely ground coffee, not quite espresso grind, but far finer than any filter grind.  (4) WDT the grounds.  (5) tamping is optional.  (6) Place a metal mesh filter on top.  (7) Lock in the portafilter and make the espresso to a 5:1 ratio.  (8) Dilute with 225g—250g of water.

On the phone with me today, Scott described this as "the only automated filter coffee approach he's willing to drink" and a "9 out of 10".

You'll need a 24g basket, a mesh screen (such as bplus https://www.bplus.biz/products/lower-shower-screen-contact-shower-screen-puck-screen or Flair 58 https://flairespresso.com/product/flair-58-puck-screen/) (hello to Flair's Andrew)

This new coffee making approach is fairly straightforward on a Decent, but you can also make it with a manual lever machine, such as the Flair, if you use a bluetooth scale and an app to track the flow rate for the extraction phase.  Both Acaia Scales and Decent Scales https://decentespresso.com/decentscale will work for tracking flow rate, and maybe other scales too.  If you don't track the flow rate at the end, Scott tells me that a too-fast flow rate will likely result, and the result is very unpleasant.  A 3ml/s extraction really is needed.

Looking forward to hearing from your results with this.
