Aroma Components of Wines from Chardonel: A French-American Hybrid Grape

摘要

Chardonel, a Chardonnay x Seyval hybrid, is a wine grape varietal suitable for Midwestern U.S. production of Chardonnay style wines. Volatile components of three Chardonel wines and one Chardonnay wine produced in Illinois were isolated by liquid-liquid continous extraction (LLCE) and headspace-solid phase microextraction (H-SPME). Characteristic aroma components were identified by gas chromatography-olfactometry (GCO) methods, including aroma extract dilution analysis (AEDA), frequency of detection (FDT) and intensity scaling. Quantification was performed by H-SPME-GC-MS. Various esters, β-damascenone, 3-methyl-1-butanol and 2-phenylethanol were found to be characteristic components of Chardonel wine.
