In wet milling, malt is steeped in a continuous stream of warm water to bring the husk moisture content up to 15%, before the malt is ground on a pair of specially designed rollers. In wet milling, the grain husk remains mainly complete, whereas in a dry mill it can fragment. This fragmentation can slow runoffs and cause quality problems.

Heat water to 158F and put it in a spray bottle or watering can, and lightly spray the grains for 60 seconds, allowing excess water to drop off. Allow the malt to sit for a minute or two to absorb as much water as possible and then mill it. Reportedly this technique results in a slightly higher water content than steaming.

Wet milling. In contrast to dry milling, wet milling consists of grinding the soaked grain and then separating the grain chemical compounds (starch, proteins, fiber, and oil). Wet milling of mainly corn aims to extract the maximum possible amount of native or undamaged starch granules. Therefore starch represents the primary product of wet milling.

So, for conditioned milling to work, the brewer needs to wet the outside of the malt but not the inside. The key to malt conditioning, then, is to quickly wet the husk, then crush the malt before the endosperm starts absorbing water. Commercially, this is most often done by steaming the malt as it is augured from grain storage to the mill.

The milling step can be conducted in either dry or wet form [9]. Dry milling increases grain comminution, which increases the yield of the brewer wort production; however, dry milling can make wort clarification more difficult [4]. Wet milling occurs in the presence of excess water (up to 45%) and promotes greater grain elasticity.
