I use a Hamilton Beach grinder. It's a rotating blade type. I want the best possible grind. Here's how I do it: after placing 1 tbs of beans in the grinder I begin grinding to a count of 5 (approximately five seconds), then I turn the grinder upside down, I then grind for 4 counts, again I turn the grinder upside down, and then grind for 3 counts.
Does that sound about right?
