The corn wet milling process separates corn into its four basic components: starch, germ, fiber, and protein. There are five basic steps to accomplish this process. First the incoming corn is inspected and cleaned. Then it is steeped for 30 to 40 hours to begin breaking the starch and protein bonds.

They are known as dry and wet milling. In the wet milling process, maize is separated into relatively pure chemical compound classes of starch, protein, oil, and fiber. The products and coproducts obtained from wet maize milling are not typically directly used by the consumer and often require further industrial processing before consumption.

Brewers' syrups, which are actually a family of products manufactured by the corn wetmilling industry, do not require a cereal cooker and can be added later in the brewing process. In some instances, this option can help resolve brewhouse bottlenecks and increase brewery throughput (Pollock and Weir, 1976; Swain, 1976; Pfisterer et al., 1978).
