Dry-milling is a process that grinds into and ferments it into ethanol with co-products of distillers grains and carbon dioxide. Wet-mill plants primarily produce sweeteners, along with ethanol and several other co-products (such as oil and starch). Wet mills separate starch, protein, and fiber in prior to processing

Timber may get wet during the milling process, or become moist if exposed to rain or dew during construction. Many timbers are commonly contaminated with Tichoderma species, which is why they should be allowed to dry before the building envelope is completed.
