Re: Dosing - Scales = Awesome, Americans = Overdos
As previously mentioned try dosing by volume.
General: Fill, and of course tamp, the pf until the top of the puck just barely touches the screw/screen when it is locked into place. Adjust the grind keeping the fill level of the pf consistent until you get the shot youre looking for.
More detailed: The exact degree of contact between the freshly tamped puck and the screw/screen will vary enormously depending on the exact model of espresso machine you have. On some the shower screen is held in place by a screw/bolt with a large head that protrudes out from the shower screen several millimeters. On others the screw is flush with the shower screen. Ideally you want the absolute minimum contact, preferably none at all, between the fresh puck and the screw/screen.
The pf should be filled enough so that when first locked on the puck doesnt touch the shower screen but as it expands during the pull it rises up to touch the screen. If you dose too low you end up with a wet sloppy puck. If you dose too high you fracture the puck when locking the pf on leading to channeling and bad pulls. Youll also clog and potentially damage your shower screen if you dose too high.
These are of course generic rules and as always the exact procedure that people end up using will be determined by their equipment, beans, and taste buds.

). The resulting puck is nice and solid with a little carbon copy of the screw head. It also leaves very little grind on the shower screen as well, which Im presuming is a good thing, not to mention some nice espresso too
