Even though the coffee pot is what brews your pot of coffee, it’s not the most essential part of making espresso. The coffee grinder is by far the most crucial piece of equipment for making your perfect shot of espresso.
We have reviewed quite a few different espresso grinders and would like to share our top five picks. We will share the pros and cons that we have found with each. We believe that it is essential that you know all sides of a product before you purchase it.

If you want a burr grinder for espresso that is easy to use and grinds your coffee consistently every time, the Breville BCG820BKSXL is the grinder for you.
This Breville model has a 16-ounce bean hopper that dumps your beans into durable stainless steel conical burrs to give you the finest ground coffee beans. There are 60 different settings that you can grind to, from ultra coarse to extra fine and everywhere in between.
The precision electric timer remembers how long you ground your beans the last time the machine was used, and runs it for the same time unless reset. This is great if your eyes are half-closed in the morning when you go to grind, but there isn’t an off switch if you forget to adjust something. You either have to wait for it to run its cycle or unplug it to get it to stop.
It does a great job at grinding, but you may want to unplug it to get it to shut off when you hear how loud it is.
In our opinion, the Rancilio Rocky Espresso is the best commercial-grade espresso grinder on the market today.
This grinder features a hopper that will hold just over ½-pound of coffee beans. The beans are transferred into heavy steel flat burrs to grind your coffee. There are 55 different settings, including slow-speed grind, that you can set for the perfect grind for the kind of coffee you want.
This machine is cumbersome, so you won’t want to move it around too much. That is difficult because it becomes clogged easily with even somewhat oily beans. You have to shake the machine to dislodge them, and that can be difficult due to its weight.
Probably the most frustrating thing about this machine is the placement of the power switch. Its location makes it hard to operate the device and handle the portafilter at the same time. It is possible; it just takes a little juggling and getting used to.
We have voted the OXO Brew Conical Burr Grinder to be the best budget espresso grinder available in stores today. Keep in mind, though, that this is a budget grinder, so it may not grind your beans as fine as you would like for your espresso. The coarser grinds will give you a weaker shot than the fine grinds will.
This grinder’s hopper holds up to three-quarters of a pound of coffee beans that it deposits into durable stainless steel conical burrs for consistent grinding. It has 15 different grind settings and a memory start timer that remembers how long to grind to get the number of fresh grounds you need for your espresso. Just hit the timer button and it will automatically shut off after that amount of time, giving you consistent amounts of coffee grounds every time.
There are a few pretty big issues with this grinder, though. Even though it has a timer for grinding, you can’t leave it unattended while grinding because the beans get jammed easily. You’ll have to shake or tap the unit on the counter to get them unstuck before it can continue grinding effectively.
It also tends to spit coffee grounds everywhere, making a huge mess to clean up. The most concerning issue is the constant buzzing when the unit is plugged in but not in use. It is loud and can be irritating.
According to our reviews, the Aromory Manual Coffee Bean Grinder is the best hand grinder for espresso. Being a hand grinder makes this the perfect mill to take with you when traveling so that you can still get your freshly ground coffee.
It features 15 different grind settings and a ceramic conical burr mill. You can grind enough for your espresso in 30 seconds to two minutes, depending on how strong you want it to be. It does take a lot of grinding, though, so it isn’t the best if you wish to make large pots of coffee.
There are a couple of concerning things about this grinder. It is made out of cheap material, so it can break relatively easily. The markings on the grind dial are hard to see, and it doesn’t always grind consistent grounds.
The Cuisinart DBM-8 Supreme Burr Grinder has an eight-ounce bean hopper that deposits the beans into the burrs to grind to one of its 18 different grind settings. There’s an electric timer to grind your coffee for the same amount of time every morning, but there’s no way to turn it off without canceling your preset selections.
The 32-cup grind chamber produces a ton of static electricity. This causes coffee grounds to stick to the sides, and you have to tap the chamber to get them to fall to the bottom. When you do this, coffee grounds tend to fly all over the place. Another annoying thing about this grinder is that after all the mess, you find that your coffee isn’t ground consistently. You need a consistent fine blend to get that perfect shot of espresso.
The bottom lip on this machine is pretty flimsy and chips easily, so handle it with care. It is also very loud.
It used to be that if you were a coffee drinker, you would buy a pre-ground can from the grocery store and use it until it was gone. These days, many prefer a much smoother and richer taste that you just can’t get from a store-bought can. Coffee beans that are ground fresh just before you use them will give you the most flavor.
When you are looking for a coffee grinder, there are a couple of things that you should know.
A blade grinder is like a food chopper with a blade that spins at the bottom to chop up your beans. Blade grinders are great because they are inexpensive, but they don’t do a very consistent job of grinding your coffee. Some beans will be reduced to a fine powder, while others remain in large chunks. If you run the blade for a long time to grind more of your beans, you risk burning your beans.
Burr grinders have two burrs that funnel the beans through a few at a time. One of these burrs is stationary, while the other is attached to the unit’s motor. Rather than slicing the beans like a blade, the burr system crushes the beans. You will still get a more substantial piece every now and then, but most of your grind will be reasonably consistent-sized pieces.
A flat burr grinder uses centrifugal force to push the coffee beans into the teeth on the inside of the burr. As a bean gets pushed further through the burrs, it is passed through finer teeth to get fine grinds. You can adjust the two burr pieces to be closer together if you want a fine grind, or further apart for a coarser grind.
A conical burr has a cylinder-shaped burr that stays stationary, and a cone-shaped burr that turns inside the cylinder to grind your beans. In a conical burr, the beans are placed in the top of the unit and use gravity to work their way down through the blades. The teeth get smaller as the bean moves through it, giving you a finer grind.
Steel has a higher thermal conductivity, so it will heat up and cool down reasonably quickly.
Ceramic has a lower thermal conductivity, so it takes longer to heat up and to cool down. Ceramic burrs tend to last longer than the steel ones do.
The most critical factor in making great espresso is how it is ground. The rich flavor comes from finely ground fresh coffee beans. The finer grind and the better consistency of ground bits will give you a better shot every time.
Make sure the one you are looking at is capable of grinding your beans as coarse or as fine as you could want.
It’s important that the bean hopper is big enough for your requirements, as you’ll want to grind your beans right before you brew. This is especially something to consider if you often have guests or if you’re a big family.
Faster is not always better. That is true for coffee grinders too. High-speed mills produce quite a bit of heat, which can burn the coffee. If you want to keep one of these units cool, you’ll have to start and stop it until it cools down again manually. Both the heat and the constant turning on/off are hard on the grinder and will cause it to wear out faster. Grinders with low-speed motors may cost you a little bit of patience, but in the long haul, you will be better off. When you are shopping, be aware that low-speed grinders are called direct-drive grinders.
