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.
Many vodka brands are simple mixtures of ethanol and water, with classic vodka composition of 40 per cent alcohol by volume. However vodka drinkers often display a preference for one brand of vodka over another. Dale Schaefer and colleagues at the University of Cincinnati and Moscow State University sought to determine whether there might be a molecular basis for this, by analysing the structural differences of five different vodka brands.
