There is a 7 step process to create Ethanol. First, the corn, barley, or wheat is milled into a fine powder. Second, the powder is liquefied by mixing it with water and alpha-amylase while heating it. Next, it is mixed with an enzyme called gluco-amylase to turn it into dextrose, this is called saccharification. It is then fermented with yeast. It is now called beer, which has about a 10% alcohol level. It is distilled to seperate the alcohol from the rest of the liquid, it is now 96% strength. It is then dehydrated to make it 100% alcohol. The final step is to denature it to make it not consumable for humans. There are co-products, making the process waste nothing. This entire process makes corn more valuable by turning it into other products worth more.
