Grain alcohol, also known as ETHANOL or ethyl alcohol, is an alcoholic beverage made from grains such as barley, corn, rye, and wheat. It is produced by fermenting the sugars in the grains, and is commonly used in alcoholic beverages like beer, wine, and spirits. ETHANOL (7 letters) is the scientific name for grain alcohol, while ETOEOT (6 letters) is an acronym for 'ethyl alcohol, the original essential oil of the tree.' Grain alcohol has a long history of use in many cultures, and is still widely used today.
