Why this matters?
Although roasting coffee is not a very visible task to the end consumer, either because you buy the ground coffee or roasted beans, it is a very important task that we must pay attention to. If you want to buy a coffee roaster machine, it’s because you surely know its importance since it changes the taste and aroma of coffee.
For this reason, many people have preferred to do the whole process at home. And, although buying a roaster for home use is not so easy, here you will have several options according to your need.
What is a coffee roaster?
It is a special machine for roasting green coffee beans; that is, beans that have not been roasted or processed. Most coffee that is ready for commercializing, whether ground or in beans, has already gone through the roasting process. Then it just needs to be packed or ground.
There are several types of coffee roasters: those that run on gas, firewood, or air, those that are industrial or more artisanal, etc.
The most important part of the roaster is the rotary drum, which will roast the coffee beans as it rotates inside the machine.
However, in industrial roasters, which are for roasting large amounts of green coffee, that rotating drum is replaced by a large tank that roasts the beans with air. It works very similarly to the air fryers we know today. Although they don’t have the rotary drum, this type of toaster has a mechanism that constantly stirs the beans during the process to obtain a uniform color and prevent them from burning.
History of coffee roasters
Its history dates back to the 15th century when coffee lovers realized the relevance of the coffee roasting degree to make the drink that was and still is very much craved by many people.
In the beginning, of course, the device was not exactly what we know today as the coffee roaster, because it was a pan with holes that was heated on a charcoal griddle.
Over the years, roasters evolved. In the late 18th century and throughout the 19th century, roasters began to be shaped as we know them today. And their success spread all over the world.
Later, in the late 19th and early 20th centuries, coffee roasters became more industrial than artisanal due to the rise of this farming product. The technological advances of the time were key to control the temperature in these large roasters and also, improve the degree of roasting of the beans.
In general, the advances of toasters and all the instruments used to prepare coffee were evolving to the same extent that coffee was gaining popularity. In addition, people who have been dedicated for years to study and make coffee were shaping the advances and needs of this industry.

How to roast coffee?
If after reading this ranking you still don’t know how coffee is roasted, do not worry! We teach you.
As we have explained throughout this guide, the degree of roasting will influence the taste and aroma you will get in your drink.
Although there are many factors that influence the final result, this is one of the first and, therefore, of the most important. Keep in mind that the brands of ground coffee you get in supermarkets at very low prices – very commercial ones, can roast the beans at very high temperatures to dull the ugly flavors of the bad coffee beans they use.
The idea of roasting green coffee, in general, is to have beans of a dark and homogeneous color. The average time will be 15-20 minutes, but this will depend on how many you are going to roast and which roaster you chose.
Here are the steps for roasting coffee in an industrial or air roaster.
- Be sure to clean the roaster very well so that there is no residue from previous preparations.
- Add the beans to the roaster and heat them to a temperature between 150 ºC and 220 ºC.
- Check the beans at 15 minutes to know if the time was enough. (Time may vary). At this point, you will be able to play a bit every time you roast the beans. We recommend you try a different time each time so that you can find the perfect point.
- Let the coffee cool. Normally, industrial roasters have another container or other function which is especially for coffee cooling. The reason is that if it doesn’t cool down quickly, the heat that is stored in each bean can continue to roast the coffee and cause a burnt bean with very bitter flavors.
- Ready, you can now enjoy a freshly roasted coffee!
If you are going to use a more artisan roaster, the process is very similar, but on a smaller scale. You should add the green coffee beans to the roaster and wait until they have the perfect color.
Keep in mind that the longer the coffee is in the roaster it will have less acidity, greater body, more bitterness and the volume of the bean will be reduced by the loss of moisture.
How to clean a coffee roaster?
Washing and maintaining very well the instruments we use for the preparation of coffee is quite important because this way we will ensure that the taste is not influenced.
If your roaster, grinder, coffee maker, filter, or other instruments have residues of previous preparations or chemicals that have formed due to use, the taste of your coffee will not be the same even when you strive to make it good.
Normally, the rotary drum of roasters is removable and therefore very easy to wash. Just remember to wash it with a soft sponge so as not to damage the non-stick and take away the lifespan of your roaster.
Conversely, if you have a pot-type roaster whose parts are not removable, you should clean it with a cloth as it can’t get wet or the engine could be damaged. It is best to use a soft cloth to remove all the residue left after using it and thus, take care of the non-stick.
If you decided to roast your coffee at home, surely you’ll have days full of aromas and flavors that will captivate your palate. Lovers of good coffee know that every detail counts and the degree of roasting, without a doubt, is one of the details worth paying attention to.
Remember that each roaster was designed to meet different needs. Make sure you know what you are looking for to make the best choice with this guide we have presented.
