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.

First, it's much faster to dry the relatively thin rough boards. Second, drying induces strains in the wood. By roughmilling and stacking the boards during drying, these strains will be (largely, most of the time) relieved. Milling a dry tree trunk is an invitation to wild distortions of the wood once it is free to move.
