Ethanol facts

Ethanol is a clear, colorless, flammable liquid with a characteristic odor, and it is the alcohol found in beer, wine, and spirits.
It is made by yeast fermentation of sugars and is used as a fuel additive, a solvent, and the active ingredient in many hand sanitizers.
Ethanol mixes with water in any proportion, but ordinary distillation cannot concentrate it beyond about 95.6 percent by mass because the two form an azeotrope.
