Though their hypothesis has yet to be conclusively confirmed, they speculate that these structural differences in different vodkas could account for slight differences in taster perceptions. The Chemistry of Vodka – Structure, Additives, and Impurities You could be forgiven for thinking there’s not a great deal that’s interesting about the chemistry of vodka. Ironically, vodka’s simplicity has made pinning down the flavor components difficult. Distillation involves the boiling of the mixture; because ethanol boils at 78˚C, it boils off before the water does and it can therefore be concentrated. After all, isn’t it essentially just a mix of two compounds, ethanol and water? All Rights Reserved. By definition, vodka in the U.S. must “be without distinctive character, aroma, taste or color,”according to the Alcohol and Tobacco Tax and Trade Bureau (TTB).

Thanks to work by Schaefer and several of his colleagues, the vodka picture is getting clearer. Further steps are necessary to arrive at the finished product, the key step being distillation. This study shows that commercial vodkas differ measurably from ethanol−water solutions. A study of the chemical structure of vodka vs ethanol has show that the difference between the two is the presence of water in vodka and the way the water mixes with the ethanol molecules in solution. Take a look at this Infographic and you’ll see that the ethanol hydrates, impurities left in or removed by filtration and additives can all affect the final product that is produced. Beverages with low structurability are likely to be perceived as watery, because the fraction of water clusters is higher than the brand with high structurabilty.” Schaefer stresses that the relationship between structure and taste is purely a hypothesis. We will analyze that alcohol evaporates leaving behind water because alcohol has a lesser boiling temperature than water. “We know from computer simulations that impurities degrade the structurability of the vodka,” he says. Most modern Vodkas are made from cereal grains including corn, rye and wheat. The spirit is so lacking in complexity, connoisseurs say, you might as well drink rubbing alcohol. Although the percentage of alcohol was roughly the same for the five vodkas studied, the “structurability parameter,” a measurement of how far the hydrate content deviated from a pure ethanol-water solution, differed. ...

Their analysis enabled the identification of small levels of ethanol-water clusters, with E•5.3H2O emerging as the predominant hydrate. As well as existing as individual molecules, the water and ethanol molecules can form structures called hydrates. “People have been struggling for years to use chemical analysis methods to understand minority compounds in vodka and basically not gotten anywhere,” says Dale W. Schaefer, a chemical engineering professor of the University of Cincinnati. Methylphenidate is a central nervous system stimulant used for the therapy of attention deficit disorder and narcolepsy. You will need to refer to this problem in the textbook for the specific structures.
