The coffee fine are a nuisance. When I pull the grinds container out of the grinder, I cover the opening with one hand and then bang the container on the counter with a cloth or pot holder to absorb some of the shock. Most of the grinds and fines come off the sides of the container. This also tends to reduce some of that pesky static electricity. Have a damp cloth to clean up the fly away fines.
Note: Have ever notices that commercially ground coffee has no fines? They save it and sell it to the pharmaceutically companies for its caffeine along with all the caffeine from the decaf process.
It’s a humidity (a lack, thereof) thing. Quick answer: Add moisture.
I handle it one of two ways:
When in a hurry (that is to say, “normally”), I put beans in the grinder’s hopper—just enough for the amount of coffee I am making right then. [Side note: I never “store” coffee in the grinder’s hopper. That works fine for a coffee shop that fills the hopper multiple times per day during business hours; the “good” shops often removing excess beans at the end of the day and storing them with their other beans in a cool, dark, air-tight container. In the spring through early fall, this is all I do, because the household relative humidity generally prevents the generation of any significant degree of static charge. In the winter, I add a drop of water to the beans in the hopper and stir with a chopstick. I grind as usual and the tiny bit of added moisture keeps static to a minimum and does not impact coffee extraction or flavor.
When not in a hurry, I dose my grinder, grind and then wait several minutes before I open/remove the bin of ground coffee. It is usually upon opening that the chaff and very fine particles of coffee “jump” out of the bin and onto the countertop or others items. Waiting a few minutes allows the charge to dissipate a bit, lessening the effect. When I (slowly) remove the bin, I gently breathe warm, moist air into the top of the bin, then quickly smack it firmly on the countertop, forcing the grounds off of the walls of the bin and helping to discharge the bulk of the static charge. Then I scoop the coffee out of the bin with my measuring scoop or I pour the grinds into whatever brewing device I am using at the time: pre-heated French press, filter cone, wire mesh or cut metal filter cone, espresso portafilter, or whatever. I might still get a tiny bit of static on the days when it is bitterly cold outside, my furnace is cranking out dry air for hours on end, and my humidifier is working its motor off trying—and failing—to keep up. It is vastly reduced, though, by simply waiting a bit and breathing a little moist air onto the grounds.
I have no brilliant secrets. I just open the little box of grounds over the sink.
How electrostatic it is will depend on the humidity. So in the summer I know I don’t need to be so careful.
