You’re Grinding Your Coffee Too Finely—Science Says So

Most coffee aficionados will tell you that grinding your own beans is the secret to making a perfect drink at home. It's true that grinding the coffee right before brewing it makes for a fresher, better-tasting beverage, but not all freshly ground coffee is alike. The model simulated how ground coffee and water interact in the cylindrical basket of an espresso machine.

Super-fine coffee is more likely to clump together and clog the cylinder, making for a less efficient brew.
