Not too long ago I posted on Home Barista about trying to find a good way to measure the density of coffee beans. 1
As always the paricipants there were way smarter than me and offered several interesting options. I dropped into the thread that this was part of my idea of a grand unified theory of espresso, and subsequently a few people mailed and pm’d me asking what on earth I was talking about and what density had to do with it.
Well, I should probably explain what I have been thinking. 2
