Dialing-in Dessini CM-14 with Keeletop/ Xeoleo Grinder
update 21 June 2025

The fastest and easiest is to use the 2-cup basket with the screen attached to the original Session basket holder. 18g of coffee beans using 1.8 grinding setting. Use the 1 cup timer for the Dessini machine which produces 36 g once the droplets end.
To simplify further, I do not throw the pre wash water, and after wash water to produce Americano 1:2 brew. Or long black if we use another glass for the espresso which is poured over the final glass filled with the pre-wash with empty basket holder, and after wash with the holder removed.
For true Espresso or Cappuccino, need to throw away the pre and post washing water or use them to warm up the glasses.
I no longer need the timer or weighing machine with these settings.

| Unpressurised creme. Locally roasted Black Panther blend of various countries. Tastes slightly sour but watery and slight bitter. This is 40 g, but should stop at 20 s, and 25 s to reduce watery and bitterness. |
 |
| Just use 2-cup setting to the end. Measured after completion. No time to stop because of filming. |
 |
| Very wide changes but consistent with 10 g beans, 3 times water sprayed. Should be 0.5 g retention, but output is 10 g because of previous grind. |
A video of the bottomless portafilter using single cup unpressurised basket. As expected from investigation of coffee residue, there is no channelling. Most probably due to the puck screen.
Another important function of the puck screen is to clean the shower head of the Espresso machine. Cheaper but less effective is to use a paper coffee filter which can be used for all types of brewing coffee e.g. Moka Cup and even French Press. Should be useful for Minipresso or other portable pressurised portable Espresso machine as well because paper filters can be cut to sizes.
I bought the unpressurised cups here:
 |
| 18 g if you use paper filter. With puck screen, only 14 g. |
 |
| I ordered this but didn't fit my unpressurised portafilter or default Dessini portafilter. |
Only the single cup fits to the unpressurised portafilter that I ordered.
I ordered my bottomless 51 mm portafilter here:
 |
| Bottomless portafilter with it's 2-cup unpressurised basket. Fits nicely the Dessini CM-14. |
A useful but actually optional is the WDT tool. A set of pins. I initially constructed mine with 5 pins stuck to a cork bottle cover bought locally. A single pin should be sufficient.
 |
| 6-pin spring-attached WDT tool. Not essential but useful. The paint came off when immersed with hot water. The pins are cleaned by punching into cloth or thin paper. |
I bought it partly because of the magnetic dosing ring. Even less useful because I constructed funnels using plastic bottles.
It is a mistake to order this type Neewer Dosing Ring because it fits inside the basket so we cannot tamp the coffee with the dosing ring attached. It appeared cheaper because it came together with a puck screen, but I already have a puck screen. Not consistent switching puck screens because they are slightly different.
 |
| Cannot tamp because dosing ring is inside the basket. |
