How do you reduce static in a coffee grinder?

Question

Is there a way to reduce/eliminate the static buildup in a burr grinder? I've tried a few different coffee grinders and inevitably on removing the grinds bin, I get a spray of coffee all over the counter.

Answer

My grounds bin has a lid. So while the grounds still collect static, they don't fly all over the place when I remove the bin from the grinder.

Giving the bin few sharp taps on the counter top prior to opening seems to shake off most of what clings to the top and sides. Then I tap out the grounds, wipe out the bin with a napkin, and I'm ready for the next morning.

Beyond that, try switching up your coffee. The cheap "8 O'Clock" stuff I keep on reserve is terribly staticy, while the beans I roast myself don't have nearly the trouble. I tend to enjoy a lighter roast, so keep that in mind - you might benefit from grinding beans with just a bit higher moisture content (of course, if you have a strong preference for dark roasts, this doesn't help much).
