The 7 Best Coffee and Espresso Grinder Reviews
There are a couple different ways to make your favorite drink, and your choice of methods will determine what accessories you need. If you want to have freshly ground espresso and the machine you choose does not have a grinder on board, you’re going to have to spring for one.
There are two kinds of grinders to consider: burr and blade.
The blade grinder will look the most familiar to you if you’ve ever had a blender. It has a blade that spins in the bottom of the grinder, and it chops up your beans a lot like a food processor does. All the beans are ground at the same time, and several times, in order to achieve the desired result of the small pieces (or grounds) you need to end up with the espresso you want.
The burr grinder is going to look a lot different and, obviously, work differently. Burr grinders are named for the main grinders (burrs), which are located inside. A few at a time, the coffee beans get between these very scratchy, flat-ish surfaces (burrs) which rub against the beans to actually grind them into small particles. When the particles are small enough, they slip through right along with their coffee ground comrades, and then they can be made into your espresso.
Without going into detail (I do that on this page – link to come), burr grinders are the better choice. But as with many things in life, better also means more expensive, which is why I also listed a couple of very decent blade grinders.
