In this study a specific taste‐modulating flavor ingredient, N ‐lactoyl ethanolamine, was determined in two Beerenauslese wines using preparative LC, as a first isolation and concentration step, followed by LC‐MS/MS on a triple quadrupole in accurate mass (AM) mode. The accurate masses of the analyte and three characteristic fragments were determined with mass accuracies between 8 and 20 ppm. N ‐lactoyl ethanolamine concentrations in the wines were 0.4 and 2.5 mg/L.
