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 coffee is wasted and there is less mess to clean up.

      I get the condensed milk and honey, but haven’t heard of using lemon peel. Maybe I’ll try it if I happen to have some extra lemon around.

        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.

        Lemon and coffee go surprisingly well together. There is a reason that espresso martinis are sometimes garnished with a lemon twist

    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!

      I obsessed over coffee for a couple years and never heard this! Maybe it wasn’t a thing then years ago?

        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

      I thought that until a $50 burr grinder overhauled my coffee. Some stuff really matters!

      It’s literally a drop. Some grinders need it more than others because they’ll make a mess of grounds everywhere without it.

        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.

          I started using James Hoffman’s tip of rinsing off a spoon, shaking the water off, and then stirring your beans before grinding them.

          Then I started taking a single bean and quick passing it under the faucet before tossing it in with the rest and shaking it around.

          Now I just have a small spray bottle I repurposed. All methods are equally simple and get the job done to keep grinds from sticking to my Encore’s hopper.

          Like others have said, it’s more subtle then slightest touch of humidity rather than actually getting anything wet.

    That’s Big Grinder propaganda to make you ruin your grinder and have to buy a new one. A conspiracy I tell you!
