How to choose a coffee grinder for home: electric or manual?


When choos­ing a cof­fee grinder, many fac­tors are tak­en into account: the type of grind­ing, the load vol­ume and finan­cial pos­si­bil­i­ties. To date, cof­fee grinders are divid­ed into two types — elec­tric (knife and burr) and man­u­al. Man­u­al ones are good for their antique appear­ance and are suit­able for big cof­fee lovers. But elec­tric cof­fee grinders are dis­tin­guished by their speed and grind­ing qual­i­ty.

Types of coffee grinder

Knife grinders

The main mech­a­nism of a knife grinder con­sists of sharp knives that grind cof­fee at high speed. The degree of grind­ing in such a cof­fee grinder may vary from the time of its oper­a­tion. And the longer the grinder grinds the beans, the fin­er the grind will be.

Knife grinder

For bet­ter grind­ing, it is bet­ter to use pow­er­ful cof­fee grinders. But tru­ly pow­er­ful cof­fee grinders of this kind are not pro­duced now. Oth­er­wise, the grains in such a cof­fee grinder would be very over­heat­ed and charred.

Most often, knife grinders are turned on by press­ing the lid with your hand. And for its work — for some time to hold the cov­er pressed or to make short press­es with your hand. In both cas­es, the grains will grind even­ly, so it does­n’t mat­ter which way you grind.

The knife grinder is ide­al for those who like cof­fee brewed in a Turk­ish, French press or drip cof­fee mak­er. Because it can grind cof­fee beans as fine­ly as pos­si­ble.

It is bet­ter to load a small amount of grains into the grinder, designed for one-time use. Do not grind cof­fee for sev­er­al days ahead. Oth­er­wise, cof­fee will lose most of its fla­vor and aro­ma. There­fore, the load vol­ume affects the choice of cof­fee grinder. Knife grinders have a bowl vol­ume of 25–150 grams. If only 1–2 peo­ple will drink cof­fee, then you can take a cof­fee grinder with a bowl of up to 50 grams. The knives in this grinder should be very close to the bot­tom of the bowl in order to grind cof­fee faster.

Knife grinders have cer­tain dis­ad­van­tages. For exam­ple, this grinder often suc­ceeds in uneven grind­ing. This neg­a­tive­ly affects the brew­ing of cof­fee in the carob cof­fee machine. Inho­mo­ge­neous ground cof­fee in such a cof­fee grinder can cause loss of taste and smell of the drink or make it bit­ter.

Anoth­er minus of the cof­fee grinder is the tem­per­a­ture increase dur­ing grind­ing. There­fore, if you grind the grains for a long time, then it is pos­si­ble not only to over­heat the cof­fee, but even char it a lit­tle. This is what leads to the bit­ter­ness of the drink and an unpleas­ant aro­ma.

To avoid all the unpleas­ant con­se­quences, you must care­ful­ly select a knife cof­fee grinder. Focus on pow­er, blade place­ment, and bowl vol­ume.

Burr grinders

In a burr cof­fee grinder, the grind­ing of grains is car­ried out by means of steel discs accord­ing to the prin­ci­ple of a mill. The cof­fee grinder pro­duces a homo­ge­neous grind, which will be the best for brew­ing cof­fee and cof­fee drinks in any cof­fee mak­er.

Burr grinder

The burr grinder is ful­ly auto­mat­ed. You just need to adjust the grind­ing lev­el and load the cof­fee beans. In burr grinders, there are approx­i­mate­ly 10–14 or more degrees of grind­ing. Cof­fee beans can be ground into either a coarse grind or a fine grind. This vir­tu­al­ly elim­i­nates the pos­si­bil­i­ty of cof­fee over­heat­ing dur­ing grind­ing.

Mod­ern burr cof­fee grinders have a huge num­ber of use­ful fea­tures. For exam­ple, you can auto­mat­i­cal­ly obtain the required grind­ing vol­ume for a cer­tain por­tion of the drink. Or the grinder itself can deter­mine how much and how many cups of ground cof­fee is enough.

In burr grinders, the vol­ume of the bowl is much larg­er than in knife mod­els. In them, it is approx­i­mate­ly 200–350 grams. These grinders are great for cater­ing and offices. They are designed for large vol­umes of grind­ing.

The dis­ad­van­tages of such a cof­fee grinder are the high price, com­plex and volu­mi­nous design.

Man­u­al cof­fee grinders

In addi­tion to elec­tric cof­fee grinders, there is also a clas­sic man­u­al cof­fee grinder for cof­fee. A man­u­al cof­fee grinder is a spe­cial item for cof­fee lovers. Such peo­ple like to make cof­fee with plea­sure. Using a man­u­al cof­fee grinder, you can enjoy the divine aro­ma of cof­fee with every hand move­ment.

Manual coffee grinder

A man­u­al cof­fee grinder slow­ly but qual­i­ta­tive­ly grinds beans. Its mech­a­nism is very sim­i­lar to that of a burr grinder. But it com­plete­ly excludes the pos­si­bil­i­ty of over­heat­ing of the grains and it works absolute­ly silent­ly. You can set any degree of grind­ing. Good for all types of cof­fee prepa­ra­tion.

Of the man­u­al cof­fee grinders, there is also a Turk­ish one. The Turk­ish cof­fee grinder is designed exclu­sive­ly for brew­ing Turk­ish cof­fee. This grinder only grinds beans to dust. The cof­fee grinder is usu­al­ly made of brass and has a beau­ti­ful appear­ance.

It is dif­fi­cult to decide which cof­fee grinder is bet­ter man­u­al or elec­tric. If you like the aes­thet­ics and the process of mak­ing cof­fee, then a man­u­al cof­fee grinder is bet­ter. But if time is more expen­sive, then an elec­tric cof­fee grinder will be the best assis­tant.

Options for choosing coffee grinders

To choose the right cof­fee grinder, you need to pay atten­tion to sev­er­al basic para­me­ters.


For elec­tric cof­fee grinders, the pow­er can reach 1300W. And the more pow­er, the greater the rota­tion speed, which can reach 18,000 rpm. But a high rota­tion speed can over­heat the grains, which is bad for taste and smell. Mod­ern elec­tric cof­fee grinders have a spe­cial sen­sor that turns off the grinder when it over­heats.


Cof­fee grinders include a hous­ing where the motor, knives or burrs are locat­ed. Addi­tion­al­ly, burr and hand grinders have a reser­voir for ground cof­fee. With blade cof­fee mak­ers, the ground cof­fee remains in the bean tank where the blades are locat­ed. At the same time, it is not advis­able to buy cof­fee grinders with a large load­ing tank for the home. Since ground cof­fee quick­ly los­es all its prop­er­ties in the ground state, it is bet­ter to store it in beans and not grind it for future use.

The case itself is often made of met­al or plas­tic. Plas­tic cof­fee grinders come in a vari­ety of shapes, col­ors and designs. Their prices are much low­er than those of met­al cof­fee grinders. How­ev­er, they are less durable. Met­al cof­fee grinders, due to the com­plex­i­ty of man­u­fac­tur­ing, have a high­er price. Man­u­al cof­fee grinders are often made from wood or ceram­ic.

Addi­tion­al func­tions

One of the most impor­tant fea­tures for a mod­ern cof­fee grinder is the abil­i­ty to adjust the degree of grind­ing. Dif­fer­ent cof­fee brew­ing meth­ods require dif­fer­ent degrees of grind­ing. For exam­ple, clas­sic espres­so needs a medi­um grind, while Turk­ish cof­fee needs a fine grind. In addi­tion, by chang­ing the degree of grind­ing, the taste can also change. You can exper­i­ment and find the best option for your­self. Good cof­fee grinders now have a large num­ber of grind­ing degrees, but for home use, only three are enough. In knife grinders, there is rarely a set­ting for the degree of grind­ing, unlike burrs and man­u­al ones.

Even mod­ern cof­fee grinders have built-in dis­penser. It allows you to accu­rate­ly deter­mine the required amount of cof­fee.

Often found built-in timers or addi­tion­al noz­zles like a blender. But for real cof­fee gourmets, it is not advised to use a cof­fee grinder for chop­ping nuts and grind­ing oth­er prod­ucts. In the future, this can affect the taste of cof­fee.

First of all, you need to choose a cof­fee grinder specif­i­cal­ly for a cof­fee mak­er. For drip, geyser cof­fee mak­ers or Turks, a knife cof­fee grinder is enough. And for a carob cof­fee mak­er, a burr cof­fee grinder is suit­able.

Sum­ma­rize. When choos­ing a suit­able cof­fee grinder, you need to pay atten­tion to:

  1. Dimen­sions and appear­ance. Now the cof­fee grinder is not only a func­tion­al device, but also a beau­ti­ful kitchen decor.
  2. The pow­er of the mech­a­nism — the greater the pow­er, the faster the cof­fee will be ground. But do not for­get about the pos­si­bil­i­ty of over­heat­ing of the grains.
  3. The mate­r­i­al of the body and parts — the bowl and knives are best cho­sen from stain­less steel. This will pre­vent the appear­ance of an unpleas­ant odor. And the case should con­sist of durable plas­tic.
  4. The type of oper­a­tion of the cof­fee grinder is man­u­al or elec­tric. The degree and qual­i­ty of grind­ing depends on the type of cof­fee grinder.
