profitability wet and dry milling ethanol. Ethanol Production Dry versus Wet Grind Processing. While dry milling is less capital intensive, it also yields less ethanol per bushel of corn than wet milling (Rajagopalan, et al., 2005). Wet milling involves steeping the corn for up to 48 hours to assist in separating the parts of the corn kernel.
