Every time I need beans I choose from the look and smell of whats on offer.
The last lot were huge beans, mild roast with a very pleasant nose (called Blue Mountain I think).
My grinder is the De Longhi with the floating top burr, which I tweaked to allow it to "almost touch" the lower half.
With this bean I found I had to set the grinder to the finest grind, and tamp with excessive pressure, to get my 6910 to give a reasonable shot. THis was bugging me. so I wrapped a couple of turns of mylar tape round the to burr carrier to stiffen things up. This improved things a bit, then I ran out of beans.
Well the next selection of beans were a very small Ethiopian bean, and to my surprise the first shot attempt blocked the 6910 completely.
I reduced the tamp down to next to nothing, but found I also had to coarsen the grind by 4 steps to get a decent pour.
Is this huge (to me) variation between beans what I should expect?
The changes to the grinder make it run a lot quieter under load, and the feel of the grind when rubbing it between my fingers seems to be much more consistent and less grainy, so Im happy to continue using it while I research a replacement.
