Volatile phenolic compounds in white wines

By gas-liquid chromatography the following volatile phenols were identified in extracts and distillates of white table wines prepared with the aid of husks and pulp used in fermentation: phenol, m-cresol, guaicol, ethyl-4-phenol, vinyl-4-phenol, eugenol, tyrosol; phenol, m-cresol, guaicol, ethyl-4-phenol, vinyl-4-phenol. The amount of volatile oils grew significantly with an increase in the number of husks in the fermenting liquid and fermentation temperature.
