It is about the process of obtaining ground coffee fromRoasted Beans: The coffee is cooled to an ultra-low temperature, ground and heated back to room temperature. This will give you a cleaner-tasting coffee.
In conventional grinding, the aromatic coffee oils contained in the bean are squeezed out of the micropores of the coffee particles. Then they oxidize upon contact with air and volatilize.
This leads to the fact that when brewing such coffeeit already contains much less aromatic and useful components. During cryomilling, the oils in the micropores are frozen and are not squeezed out during grinding, but, on the contrary, are stored inside the particles.
The grain was frozen to -100 ° С, ground and comparedwith grinding at room temperature. The grindings were different in their appearance. With the naked eye, it was seen that the grinding at room temperature is more humid, and the cryomilling is dry and crumbly.
