The fracturing and friction of coffee beans during grinding generates electricity that causes coffee particles to clump together and stick to the grinder. Researchers report Dec. 6 in the journal Matter that coffee beans with higher internal moisture produce less static electricity, which means less...
Use a mister bottle and give your beans one(1) spritz per 20 grams. In those cases the amount of water should be small enough that it will completely dry before rust can develop
Hear hear! I used to grind beans with a regular old blade grinder, and the resulting grounds were always really inconsistent; half of it would end up really dine, almost like a powder, and it would take forever to brew and would sometimes clog the filter. The burr grinder I picked up cost more, but it was worth it. I'm never going back, blade grinders suck.
Any black coffee, including instant, will taste gourmet with a bit of lemon peel, honey, and, if you're feeling fancy or need something a bit sweet, a nice dash of condensed milk. Try it next time you're at a meeting where they only have shit tea and coffee, you'll thank me later.
The lemon trick was a common thing in the 20th century to help mask the bitterness of improperly brewed or processed espresso, but it’s died out since production and brewing of coffee has been refined in the modern era. Still an ok, calorie-free way to liven up some shit coffee.

Very tiny amounts of salt will also make low quality bitter coffee a lot more palatable and help you use less sugar, so I assume the sourness of the lemon probably has a similar effect. And when I say low amounts I mean like maybe 50mg of it for a large cup.
Ideally you use a spray bottle. Just give it 1 or 2 pumps, tops, then shake it about. The surface of the beans will still look and feel essentially dry.
Been normal to do this in coffee circles for a long time. It does not affect the burrs enough to detect.
You don't do this in a coffee shop or if you're grinding dozens of times a day, but most people are only doing 1-2 a day tops and that's just not enough moisture to matter.
This has been “known” for a long time but glad to see a formal study confirming it!
I often splash the handle-end of a spoon with water and stir the beans with it before grinding. Makes a big difference whether you’re making espresso or otherwise!
The reason I like it is it reduces all the static when it comes out of my burr grinder. So it’s not clinging to everything and it’s easier to get my grinds from one place to another without making such a mess
