wet milling | Craft Beer & Brewing

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 run-offs and cause quality problems.
