(Wiley) Vodka tastes different from brandy, and connoisseurs can distinguish among different brands of whiskeys. The flavors of spirits result from a complex bouquet of volatile compounds. New colorimetric sensor arrays on disposable test-strips read by hand-held devices allow for their rapid, inexpensive, and sensitive identification by their chemical 'fingerprints'. They are based on novel sensor arrays that detect and differentiate among a diverse range of aldehydes and ketones, as reported in the journal Angewandte Chemie.
