The next item in our series? A coffee grinder.

Professional: Jonathan Jarrow, owner of Harbinger Coffee in Fort Collins, Colorado.

Pro Tool: EK 43 Mahlkonig coffee grinder.

Why it’s a Pro Tool: “It cuts apart the coffee particles in a very even way… We are able to get more intensity of flavor, more clarity of flavor than a lower quality grinder.”
