Compare the Best Coffee GrindersOctober 2018

At its core, a coffee grinder is a small machine that take whole coffee beans and runs them through a grinder, providing fresh ground coffee for an excellent brew. While it’s definitely fine to use pre-ground coffee, coffee snobs generally agree that coffee tastes better when you use freshly-ground beans rather than pre-packaged grounds.

Blade grinders

These grinders use sharp blades powered by an electric motor to chop the beans into very fine pieces. These machines are generally the cheapest type of coffee grinder, but they do not produce a particularly even grind - some ground may be significantly different sizes than others, leading to a less-efficient brewing, and less tasty coffee. More troubling, the high RPM of the blades on these type of grinders generates quite a lot of heat, which can lead to actually burning the grounds, making coffee brewed from them taste far more bitter.

Burr grinders

This method of grinding is the traditional way of grinding coffee, and has changed very little since the manual grinders that used to be used. The ‘burrs’ in question are toothed or notched gears, which crush and grind the beans into a uniform manner. They give a far more consistent grind than blade grinders, but tend to be slightly more expensive. Burr grinders also improve on blade grinders by being able to vary the size of the grind, allowing them to be effectively used for a wide variety of coffee brewing methods.

There are two main types of burr grinder: conical and wheel. Conical grinders are quieter but also slighly more expensive than wheel grinders.

Grind Settings

Burr and disc coffee grinders have settings to change the size of the coffee grounds produced by the machine. This is important because different types of brewing methods favour different sizes of grinds - an espresso machine requires an extremely fine blend, whereas using a cafetiere requires far coarser grounds. Many will have pre-programmed settings to allow for easy selection, but will also allow manual adjustment.

For bladed grinders, it is more difficult to adjust the side of the grind, since the blades cannot be modified to cut coarser or finer. However you can gain an approximation of different grind sizes by grinding the beans for longer. As a good rule of thumb 8-10 seconds will give you a coarse grind, with 12-15 seconds giving a medium grind, and 15-20 for a fine grind.

With all types of grinder, you have to experiment a bit to find the perfect grind setting for the coffee you want to make. If you find too many ground leaking into the coffee, try a coarser grind. If you want a more intense flavour, try finer grounds.

Capacity

Coffee grinders all have a different capacity, measuring that amount of ground coffee the machine can hold. Some grinders contain a big hopper that can hold enough grounds for several cafetieres, others will only product enough grounds for a single cup - these usually have inbuilt ‘dose controls’ to make sure only the right amount of grounds are produced at once.

Which capacity is best for you depends on what kind of coffee you mot regularly make - families and companies may prefer a bigger capacity, while solo coffee drinkers may only need a grinder that dispenses a single dose at a time.

Timer

More advanced coffee grinders will allow you to set a timer for how long the grinder will run - this allows you to create the precise grind quantity for the amount of coffee you want to make, especially when using bladed grinders. Some coffee makers will measure out in seconds of grinding, others will measure in cups. In both cases, you will need to experiment to find the right amount of coffee grinds for your chosen method of brewing.
