For a 27 second shot pour with 18 grams of coffee:
1) I find that if i single dose it, I have to put the grind setting to super fine at the number 1 on the dial. I do not like this setting because my espresso tastes flat with no brightness.
2) If I keep about 60 grams of beans in the hopper, then the grind setting can be placed at a less fine grind setting at number 4 on the dial. I prefer this because my shot will taste more bright.
I prefer #2 because I like to keep my shot flavor at that.
The problem is, how do I dial around the #4 area without wasting a ton of coffee? With my compak k3 old grinder, I could dial in with single dosing and then place the beans in the hopper and keep pretty close to the same setting. With the Caedo, just a quick second will grind a lot of coffee and a second isn't even long enough to move the dial.
Would it be horrible if I moved the dial adjustment without the burrs running?
I adjust my dial when it is off. Currently, I am coming close to the blanket rule brew ratio of 1:2. I am between 2.5 and 3 on my Ceado but please keep in mind all beans are not the same regarding roasting. Therefore, I know my grind settings will always change.
To save beans ... You can see what I did with my Ceado E37S. I do not use the bean Hopper at all. I specifically use the Ceado for double dose grinding with the ECM synchronika tamper covering the bean chamber after I load 18 grams of beans in it. COOL NOTE: Of all the times I've been doing this (about 100 so far) , I have received very close to zero retention on the beans grinded. I am truly satisfied. To see this in action ...
