Study on Volatile Compounds of Cabernet Dry Red Wines from Different Production Regions in China by DPS Software

Wine aroma is an important aspect of wine quality. The 21 main volatile compounds contents of Cabernet dry red wines from Helan Mountain, Ji County and Changli County of China were determined by HS-SPME (headspace solid-phase micro-extraction) and GC-MS. The result of GC-MS showed that the contents of aroma compounds of Cabernet dry red wines from three production regions were different. Based on clustering and principal component analyses of 21 aromatic constituents by DPS V7.55 software, 8 major contributors were determined as ethyl caprylate, pelargonaldehyde, heptanol, phenylethanol, ethyl isovalerate, benzaldehyde, citronellol and hexyl acetate. They had grass, flowers, fruits, lilac, and cinnamon aromas.
