The present invention is a test milling method to determine the suitability of a grain for use in the derivation of desired end products. A full scale mill is simulated through a bench scale application wherein only a small portion of grain is required to conduct the test in contrast to testing protocols which employ full scale equipment. By utilizing the small scale simulations, hybrid varieties may be tested for total grit extraction and total yield well in advance of the many seasons that it takes to develop market quantities of a hybrid. The invention also relates to a method for determining which items of data collected are needed to accurately predict the total yield and grit extraction % and subsequently applying these limited data points in a shortened simulation to reduce the number of steps required in the test protocol. Data obtained from such tests may be used to direct hybrid research and select the best hybrids and shipments for the desired milling process.
