There are many factors that affect the final quality of coffee, and high-quality, clean coffee brewing equipment is definitely one of the important guarantees for high-quality coffee. If you want to pursue high-quality coffee, the initial investment is necessary, but you have to remember that having high-quality brewing equipment does not mean that you can make high-quality coffee. In just a few simple steps, you can break through the bottleneck of coffee brewing, give full play to the potential of yourself and your equipment, and make truly perfect coffee.
Below I will bring you some tips for cleaning coffee grinders. You may think that I am writing this article because I have cleanliness and obsessive-compulsive disorder, and think that repeating these steps is boring and tedious and lacks fun, but I firmly believe that regular cleaning of the coffee grinder is absolutely necessary. When the taste of coffee continues to perfect, you will feel that all this is worth it. Whether you are a professional or a home barista, I recommend you try to clean the coffee grinder according to my method. I guarantee you will be shocked by the outstanding quality of coffee.
Before discussing the specific methods, let me explain to you why you need to clean the coffee grinder and the benefits of doing so. In the final analysis, we have to return to the most basic elements that affect coffee taste: oxygen and heat. Don't think that this has nothing to do with coffee grinding. The oxygen and heat during the grinding process will also have an important impact on the heaviest quality of coffee.
Oxygen and heat
Coffee is an organic and perishable product. Coffee deteriorates very quickly when exposed to air and heat. The longer the coffee is left in the coffee mill, the longer the contact time between the coffee and the oxygen and heat source will be, and the coffee will also become difficult to swallow. If it is cleaned irregularly, most coffee machines have more or less residual coffee powder inside, which means that the coffee beans you grind each time are not 100% fresh.
The principle and technology of grinding
The way the coffee grinder grinds coffee beans may be different from what you think. You can control the thickness of the powder by adjusting the button on the grinder, but the ground coffee powder will never be uniform. All coffee powders are different in size. To put it simply, most of the coffee powder ground by high-quality coffee grinders can meet our expectations, and only a small part is too coarse or too fine coffee powder.
Among them, ultra-fine coffee powder is the main reason why you must clean the grinder. Since these coffee powders are very, very small, they will deteriorate faster when exposed to oxygen and heat. At the same time, these fine powders will mix with oily substances and stick to the grinder. Over time, the coffee powder sticking to the grinder will form a shell, which will give the ground coffee powder a roasted peanut flavor. I dare say that all coffee ground from an unwashed coffee mill has this taste. I assume that you have not encountered the same experience. As long as you clean the grinder regularly, you can completely get rid of this boring taste!
Another reason why we must clean the coffee grinder comes from the working principle of the grinder itself. Most high-quality commercial or domestic coffee grinders contain a small amount of coffee powder. The remaining coffee powder will be pushed out during the next grinding and mixed with the freshly ground coffee powder. Many people are unable to perceive this and ignore the serious consequences that this process may cause.
To avoid this phenomenon, some household coffee grinder manufacturers are studying how to reduce the residual coffee powder in the grinder and make the process of cleaning the grinding blade easier than commercial grinders. Before they invented a new type of grinder, all we could do was clean the grinder regularly. Whether to clean or not depends on your time and energy, but I believe that no one wants to taste the perfect taste brought by higher quality coffee!
