Discovery Channel Uses Chromatography to Find Authentic Tequilas
The Discover Channel website reports that in response to the many counterfeit tequilas being produced today, researchers are using ion and gas chromatography to analyze tequila samples and compare them to the impure mixed "tequila" types. They found the authentic drink, which is regulated by strict standards in Mexico, has noticeably higher levels of certain chemicals, including methanol, 2-methyl-1-butanol, and 2-phenylethanol

The researchers say that using this technique - along with Fourier transform-infrared spectroscopy (FTIR) or molecular fingerprinting - will help to make sure your margarita is the real deal. The findings of the study will be detailed in an upcoming issue of the Journal of Agricultural and Food.
