I don't know much about horses, but I've been given to understand that dead ones do not respond to even the severest of beatings.
Disclaimer above. I have had countless grinders over the years and just added to my arsenal a Eureka Zenith 65. The burrs are as they were when they left the factory - rough and unseasoned. In my joy and impatience, I took the best coffee I have and went ahead and pulled a shot. It tasted beautiful. The taste was not what got me puzzled.
After a few pulls and getting the grinder where I wish it to be, I found that the consistency is all over the place. I'd pull a shot and be forced to adjust the grinder two shots later - several times during the same session. I tried looking on-line for the explanation but I drew blanks. I wish to find out what it is that makes the adjustment wander. I'm baffled that I have to adjust finer and the go coarse in two shots.
Can someone please explain in 'six-year-old-child' terms how and why this is and how it happens. I have never had to struggle this much with a grinder before.
