drying process is key as well
once the germination phase is done, which allows the enzymes to form to break down those starches during mashing, the drying phase reduces the moisture content of the grain, allowing proper milling and cracking of the endosperm, as well as allowing proper storage without mold and mildew setting in, plus creating flavors and profiles you would never achieve from a wet/still germinating grain
the germination phase is extremely important as well, moisture contents, time, temperatures, basically 72 hours of constant changing parameters to ensure proper germination to allow for maximum sugar extraction
Or, instead of malting any of it, you can throw it into a cereal cooker, or decoction mash it, and try to work with it that way, although temperatures are very important here as well depending on the type of grain you are decocting
