If coffee beans are pre-ground, the aromas they contain react with the air and evaporate. Airtight packaging slows down this process, but doesn’t stop it. If you want to enjoy the full flavor of the whole bean, a coffee grinder is recommended.

The roasting process gives coffee beans an intense aroma that is stored inside. If they are then ground and thus broken up, the ingredients escape and (when brewing) develop their full taste. For this reason, the beans should only be ground when you want to drink a coffee. Pre-ground varieties do not offer this option, but whole beans do. Provided, of course, that you have a suitable mill with a cone, disc or impact grinder. In this article you can find out how the grinders differ.

This is where common grinders differ

An electric coffee grinder is used to finely grind whole beans without heat. This is made possible by its integrated grinder, which is driven by a small motor. Depending on the manufacturer, coffee grinders are now equipped with a conical or disc grinder, in the past even a percussion grinder was installed. But what exactly do the terms actually mean and how do the grinders differ? We’ll tell you:

cone grinder

One works differently than the two following grinders Coffee grinder with cone grinder Particularly gentle: Due to the low speed, the beans are only exposed to low heat so that they retain their full flavor. They are processed into a fine powder by being ground by a rotating cone (also called a conical grinder). Gravity plays an important role in this. The smaller the distance, the finer the result. For this reason, the coffee grinder with a conical grinder is often preferred to the other models.

disc grinder

Two discs, one on top of the other, curved inwards, grind the coffee beans into a fine powder. This is made possible by the fact that the distance between the toothed discs decreases from the inside to the outside. speak, one Coffee grinder with disc grinder (made of ceramic or steel) uses centrifugal force to achieve an even result. You determine how coarse or fine the coffee powder should be by the distance between the discs. The only drop of bitterness here is that the high speed generates heat, which unfortunately can have a negative effect on the aroma.

impact grinder

While it was still common practice in the 20th century to equip coffee grinders with impact grinders, this construction technology is now outdated. And there is a reason for that: Unlike cone and disc grinders, the beans are crushed by a rotating stainless steel blade, like in a blender. This creates so much heat that the coffee gets a bitter taste. In addition, the finished coffee powder is often ground unevenly. The only positive thing is that one Coffee grinder with impact grinder is cheaper to buy than its more expensive successors.
