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.
Burr grinder 4 lyfe.
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.
We got literally the cheapest one off Amazon for like $40, and it’s brilliant.
