In the process of production, grains are roasted using French "dark" method, after which the grains become very dark and acquire a pronounced aroma. The next step is coffee grinding, which is poured with boiling water, and the resulting concentrated "drink" goes through the process of "dry freezing" or sublimation and is crushed into granules.
That's why instant coffee Mr. Viet is also called freeze-dried: the process of sublimation, i.e. sharp freezing, is the basic principle of creating such coffee. This is an exclusively natural product that has a taste and aroma no less bright than ground coffee and coffee beans.
