Ethanol is an [[alcohol]] [[oxygenate]] that is added to [[gasoline]] to increase the [[octane]] rating. The product is produced through the [[fermentation]] of [[corn]], or other cellulosic material.

A by-product of the fermentation process is [[distillers grains]] which can be used as cattle feed.
