If espresso prep is a primary element of your business, then choosing the right coffee grinder for the job is essential. In fact, you may recall us harping on this concept before, but your coffee grinder truly is the most important piece of equipment. The grind is the thing. To assist in your consideration process, we have produced another grudge match between two fairly similar-grade commercial coffee grinders: New kid on the block, the Rancilio KRYO 65, versus one of the more popular mainstays, the Mazzer Super Jolly. Watch as Brandon guides us through how they compare, specifications-wise, and then perform a few functional comparisons: Do they produce the same volume of coffee in 5 seconds? Does the KRYO's aluminum fins make a difference in the grind temperature or consistency? Watch as we put these two mid-range coffee grinders to the test!
