Extraction of shallow roasted coffee

Light roasted coffee (Light Roasting Coffee) refers to the degree of roasting from the first explosion to the second explosion in the baking stage, that is, the roasting of cinnamon to the city. The main purpose of shallow baking is to enjoy the variety of aromas contained in raw coffee beans. In other words, it reduces the aroma of coffee formed during deep roasting and highlights the characteristics of raw beans. So the key point of choosing shallow roasted coffee lies in the freshness of raw beans and the rich aroma of raw beans. Basically, the more advanced the coffee market or raw beans, the easier it is to come into contact with light-roasted coffee.

For light roasted coffee, the coffee cell tissue has not been fully expanded, and the capillaries that assist in the extraction of coffee have not been fully formed. So the sour taste is more prominent. If the usual extraction method is used, the good taste may not be fully reflected. Several changing processes are added to the basic extraction method in order to get a good coffee with more flavor.
