Swirl, sniff, sip, and swallow: Discrimination of different wines has always been a matter of tongue and taste. Is objective and reliable discrimination of the thousands of wine varieties possible by means of a simple chemical analytics kit? Scientists in Heidelberg, Germany, say yes, and in the journal Angewandte Chemie they present two polyelectrolyte semiconductors that in combination form a simple fluorescence-based analytical technique to discern at least thirteen white wines.
