I think lee was referring to a standalone Cuisinart brand burr grinder.
I have done this on one occasion when I had a couple pounds that needed grinding at once–they were happy to oblige. It only costs the price of a cup of coffee and even that was not required.
Agreed. Burrs are vastly superior to blades and need almost no maintenance. As well as being inexpensive.
Somebody might be able to get the cheapest possible blade grinder for $5 less than the cheapest possible burr, but the moment you introduce “cheapest possible” into the conversation, you’re already setting up to do something stupid.
I’ve done this at Starbucks too. I did buy some coffee but the were happy to do it.
I’ve never been able to find a grinder that and adequately make an espresso grind. Even on the finest setting, the grounds are too course. I’ve tried several. I have a dedicates spice grinder that has the same problem.
My burr grinder has many settings that grind too fine to make decent espresso out of the powdered results. And my espresso machine is a Rancilio Silvia, so yes, it’s a competent espresso machine.
Try a Rancilio Rocky burr grinder. I think it’ll reduce the beans down to their compotent molecules.
The grinding plates on most home burr grinders are too small to do a decent job at that. To some extent the manufacturers can compensate for the small size by making parts to a tighter tolerance, but then you get clogs etc.
Whirling blades are the way to go for home brewed espresso.
Are you sure it needs to be taken apart and cleaned? Any residual grounds on the grinding surfaces will presumably work their way through with the next grind. I have never taken apart and cleaned our coffee grinder, and it works just as well as the day we got it.
