The most important point in the selection of the bean grinder is to be able to grind the coffee powder with uniform particles, otherwise it will do great damage to the coffee flavor, even if the characteristic coffee beans are unevenly ground and the extraction is inconsistent, so that the taste is so messy that it is unable to present the appearance it should have.

Hand-held bean grinder is elegant and retro in shape, and most of them use cone knife grinder, which is the most favorite household bean grinder for experts.

The quality of the bean grinder mostly depends on its own design, especially the grinding blade, which crushes the beans by squeezing through two knives. In addition to being able to grind a uniform powder, whether the beans can be ground in a short time, so as not to affect the quality of coffee beans due to friction heat is also one of the factors that must be measured.

The bean grinders on the market can be divided into hand-type, propeller-type, disc-type and cone-type. Generally speaking, hand-shaking and propeller-type bean grinders are mostly used in household use. The grinding uniformity of propeller-type bean grinders is generally poor and easy to heat, but if convenience is taken into account, it is a suitable choice. The hand grinder is designed to maintain the quality of coffee beans, and if you can enjoy the manual process, it will be a really good helper for making a good cup of coffee.

The last factor to consider is the applicability of the bean grinder. Different models have slightly different adjustments for different thicknesses. Before selection, you need to measure your usage habits. If you often need to adjust the thickness scale, or if you require a slight difference in particle thickness, you must choose a model that is convenient to adjust or has a finer range of thickness setting.
