Thanks to work by Schaefer and several of his colleagues, the vodka picture is getting clearer. 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. Every company is advertising triple distilled, quadruple distilled, and so on, to give you the impression that the vodka is the best distillate possible. Not you? But, it’s also the No. Vodka on the other hand is a simple mixture of ethanol and water, a classic vodka composition is usually 40% alcohol (ethanol) by volume. Ironically, vodka’s simplicity has made pinning down the flavor components difficult. Although chemists have spent years ruminating on the hundreds of flavor molecules in a bottle of scotch, vodka has remained elusive. Chemical engineers could begin to modify and manipulate specific impurities to garner more enjoyable structure collections. What's nitro cold brew, and why is it so damn delicious? Res. Further steps are necessary to arrive at the finished product, the key step being distillation.

Theoretically, all vodka brands should have the same faint or undetectable taste as the liquor represents a solution of 40 per cent pure ethanol and 60 per cent pure water. American and Russian scientists studying the molecular structure of vodka have suggested that our choice of spirit could be influenced by its molecular make up. Alcohol evaporates because of its vapor pressure and therefore, its molecule lying at the surface of alcohol (liquid-gas boundary) breaks its hydrogen bonding and tends to escape out of alcohol solution. 93, 10 September 2004, pp. 201–205. 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. Clusters of water and ethanol molecules, known as hydrates, were found to be structured differently in one brand to the next, which might perceptibly affect how much someone enjoyed the vodka — one might feel more watery than another, … We source our quinoa directly from local farmers in Peru, and handcraft our vodka by cooking, fermenting, and distilling in 45-gallon micro-batches.
