It blows my mind how everyone is trying to extract coffee without first measuring how hard it’s going to be, and then not using the full range of all their tools. Avoid bitter over extraction, and sour under extraction, by measuring the density.

There have been several requests for SSDI to include grind settings for each density. There are several problems with this. Different espresso basket diameters have different coffee bed depths, which requires different grind settings. For example a standard 58mm basket will require a much finer grind than a 45mm holding the same amount of coffee. …
Excuse the terrible pun. I want to thank Logan Collinge of Mojo The Beanery for spending several weekends roasting to order for me, and being such a mine of information.
