Aroma Constituents of Muscadine Wines1

Welder and Noble muscadine wines were analyzed for their volatile aroma compounds with a combined gas chromatograph‐mass spectrometer. Higher alcohols and esters of fatty acids were numerically the largest groups of flavor components identified, with many of these compounds present in both Welder and Noble wines. The relative concentrations at which they occured in both wines were however different. The more intense peaks appeared in the Noble wine in most cases. 2‐phenylethanol which is often present in muscadine grapes was also identified in the wines. A gas chromatogram of the wine extracts are presented, along with a Table of compounds and their associated mass spectral data.
