Also referred to as ethyl alcohol, grain alcohol or ETOH, ethanol is a clear liquid with an agreeable odor. Ethanol is made by fermenting and distilling simple sugars. Today, ethanol is a fuel produced from crops such as corn, grain sorghum, wheat, sugar and other agricultural feedstocks. Most fuel ethanol produced in the U.S. is derived from corn. Latest figures indicate that almost 40 percent of the U.S. corn crop is dedicated to ethanol production. In Brazil, the world’s top producer of ethanol, sugar is the primary feedstock. Since it is produced from crops or plants that harness the power of the sun, ethanol is considered a renewable fuel. Pure fuel ethanol contains chemical properties identical to that of other grain alcohol. As such, it must be denatured or made unfit for human consumption. In the U.S., the most common denaturant is gasoline.
