Thirty-eight California and French wines were analyzed for y-nonalactone by Freon extraction and gas chromatography. The California white wines had from 0 to 16 pg/L (average for 6 samples was 7 ~lgl L and the red wines from 12 to 43 kg/L (average for 20 samples was 24 t&L). French red wines obtained similar amounts, 14 to 41 p&L (average for 12 samples was 21 p&L). The sensory threshold for ynonalaconte was determined to be 30 kg/L.
