    Re: How much to dose

    I started by weighing each grind separately so that I could get the tamp and grind coarse/fine correct.

    Now that Im using different beans and roast levels Im noticing that the same volume of grinds can weigh anything from 20 gm to 23 gm.

      Im not sure what you mean by chopping sorry? Do you mean sweeping the coffee over the basket but not sweeping it off, and sweeping back the other way etc to fill the basket thoroughly?
      yeah thats about it a sweep back and forth and a bit of a chop up and down. I use finger / scoop / anything in reach....

      my machine does not like overdosing to much so my chop just helps my distribution.

      if i dont chop i think it might get a puck prone to more channeling around the edges if my tamp is light. I have been grinding finer and tamping less (lighter) so hence my need to chop for distribution in my low (underdose?) dose

      imo in the end its what works for your machine and cup

        This is just a newbie talk but I think its all in the law changing one variable at a time.

        1. dose consistently.
        whether it be 14g, 20g or i fill the basket up till there. Do it with a scale or visually. as long as its consistent.

        2. tamp consistently.
        same thing. do it with a scale or just feel it. but make it consistent.

        3. once you dose and tamp consistently, all u need to do then is adjust the grind.


        Do i get this right?

          No and YES..

          If ya change ya Grind then ya dose and tamp may well have to change as well...

          OH... A new batch of different beans... Yep it all changes again.

          The trick is to then manage the ONE variable that you wish to change FIRST... It may be that after ya change ya grind... It gushes... So then you might change ya tamp and see how it goes, then a little later you may need to change ya dose; and then back to square one.

            Well basically its just practive. Some machine are really sensitive and require a certain level of dose in the filter basker. For example the sunbeam em 6910 likes to have the filter basket updosed so when you tamp you can see half of the steel on the SB tamper. Other machine, maybe like the silvia requires a normal or low dosing.

            I have a theory which is as you move upto to more expensive machine you will see they are more forgiving on you dose .i.e. dose levels.

            I know this from the machine i use at work. 9 out of 10 i will get a good shot no matter what the dose or tamping. Its a commercial 2 group machine. Its hard coming back to the 6910 because you have to be really carefull how much you tamp and dose but still still love my SB 6910. ;D

              Strange.
              I never found the 6910 to be that fussy.
              Maybe I just got the hang of it easily.

                I agree.... I either got teh hang of it or the SB was more forgiving...

                  Am not sure about the concept of dose consistently... Is there not a science to the amount of coffee brewed in espresso that extracts the right amount of flavour/volume/in the right time etc? i know 2+2 is gonna come in here :P, but to me it seems a bit strange to say it doesnt matter at all how much coffee youre using, just be consistent...

                    Re: How much to dose

                    I also find that when i updose the basket (comes to about 19-20grams in the basket), when i observe the puck in the basket, there seems to be a slicing or a tear on the top right side of the puck (with the handle facing towards me)... is that normal? It looks like a few holes have been dug in, but not too deep. During the pour however it didnt seem to have any signs of channeling though... nor did the bottom of the puck look channeled if it is supposed to...
