Vodka
History

Scholars debate the beginnings of vodka because there is little historical material available. For many centuries, beverages differed significantly compared to the vodka of today, as the spirit at that time had a different flavor, color, and smell, and was originally used as medicine. It contained little alcohol, an estimated maximum of about 14%. Distillation techniques were developed in Roman Egypt by the 3rd century, but the description of aqua ardens ("burning water", i.e., alcohol) made by distilling wine with salt appears in Latin works only by the 12th century. The process was well known among European medieval chemists by about 1300.
