I tested the Ninja AutoBarista Pro, and its smart Grind iQ feature demystifies grind settings so you don’t have to master coffee science for a decent latte

Before I tested and reviewed the Ninja AutoBarista Pro, I had tried every kind of coffee brewing method over the years. I ground my own beans with a high-end 20-setting electric burr grinder. I researched how to get the ideal grind for each type of bean and brewing method. Grind size is important, because it determines the speed that water flows through your coffee grounds and therefore the amount of extraction.

As a general rule, you’ll want a coarser grind for a French press or for cold brew made in the refrigerator. Medium-coarse works well for pour-over. A typical automatic drip machine works best with a medium grind. A moka pot works well with medium-fine. The finest settings are best for espresso machines or Turkish coffee.
