    Compared to my megacrem that pick looks underdosed, I generally dont like to see the ridge in the basket. But as others have said it is whats in the cup that counts, if it tastes good then you are on the right track.
    ?That seems contradictory?
    It does seem underdosed to me too, but the ridge......?

      The ridge in the basket is the bit that holds it in the grouphandle. If I can see it after I have tamped I wouldnt expect a good shot.

        To the ridge means to the top of the channel in the wall of the basket (about 3 to 4mm from the top of the basket) - and not to the top of the basket

        Its also helpful to time your shots - 30ml from a 30sec extraction with the correct dose and grind, will usually generate a pretty good result - this is not the gospel truth - but its a pretty good rule of thumb

        I also like to weigh my grind (occasionally) to see how much Im putting in the basket and to measure for consistency

        See how you go with the above

        From experience the Megacrem has low(ish) shower screens and doesnt like to be packed too tightly or too full (same thing really)

        Cheers,

        Pat

          KK for example tamps his old system and it had about 8mm between the top of the basket and the puck..

          My personal experience is with the Galatea and the BZ40

          Its fair to say that its same for most Bezzera machines
          A tamp of 8mm is required for correct clearance  
          It does not matter what basket you use, the tamp depth stays the same

          So if you like stronger coffee use a larger basket

            @ moto coffee
            Sorry, I misinterpreted ridge as the ridge that you can see made by the group head. Makes sense now.

            @ askthecoffeeguy
            Yes, the shower screens are fairly low.
            To go back to part of my original question, if theres a large indent being made by the side of the shower screen, I assume that means the basket it overpacked?

              Yes
              It should clear the screen by a hairs whisker
              You will get away with a very light touch but thats about it
