USDA’s latest grain crushings report put August corn use for ethanol at 432.3 million bushels, down 3 percent from July and up 4 percent year over year. Cumulative use during the 2021/22 corn marketing year was just slightly below USDA’s estimate in the September WASDE, which was 5.330 billion bushels, but about 2 percent higher than the volume USDA was forecasting last September at the start of the season.

Over 92 percent of 2021/22 corn use for ethanol was from dry mills, a record share. Wet mills used a total of 409.8 million bushels during the marketing year, down from 454.2 million in 2020/21 and 556.8 million in 2016/17, now likely the highwater mark for wet-milled ethanol production.
