A novel method for authenticating sake and combating potential beverage fraud (IMAGE)
Caption
Researchers from Japan explored stable isotope analysis to authenticate sake and distinguish different sakes from different breweries—they measured oxygen and nitrogen stable isotope ratios in the nitrate content of sakes using denitrifying bacteria. This method could potentially combat the global issue of sake fraud.
