What grain is used in ethenal?

Ethanol is primarily produced from corn in the United States, where it is fermented from the starches in the grain. Other grains, such as wheat, barley, and sorghum, can also be used to produce ethanol, depending on the region and availability. In some countries, sugarcane is another common feedstock for ethanol production. Overall, the choice of grain varies based on local agricultural practices and economic factors.
