Coffee is also distinguished by grinding, grinding finely or large, depending on the brewing method. For about a hundred years, people have processed powdered coffee, just put in boiling water to drink. Powdered coffee is prepared in two ways: freeze drying or spray drying.
Both must be pre-filtered to draw all the essence and then spray out into tiny particles to dry. Many new techniques have been tested to prevent the powder coffee from deforming and losing its smell. However, fastidious people still believe that powdered coffee can not be equal to brewed coffee.
