Because we cannot use more than a limited number of sieves in a single stack, the methods for analyzing the particle size data presented in Chapter 34.1 will be discrete in nature instead of continuous; thus, histograms will have a relatively small number of bins and a cumulative distribution will consist of a discrete number of points.

The traditional method for coffee particle size and size distribution measurement is sieving. However, sieve measurements are slow and do not correctly assess the percentage of fine material within the coffee grind, leading to variations in the brew strength. Laser diffraction particle size analysis is a rapid alternative to sieving, providing:
