Why does the basic knowledge of introduction to Coffee emphasize freshly ground Coffee

When you smell the fragrance of coffee powder, it shows that it is deteriorating and the essence of coffee is decreasing. If the diameter of the coffee powder is doubled, the volume of a single particle is reduced by 1 × 8, and the surface area of the corresponding total coffee powder is doubled. After the coffee bean is ground into coffee powder, its surface area increases exponentially, and the area of contact with air increases hundreds of times.
