Californian Chardonnay was stored in five different wine packaging configurations at three different temperatures for a period of three months to study the combined packaging temperature effects on the sensory and chemical properties of the wines. A trained descriptive panel evaluated aroma, taste, mouthfeel and color, and the results were correlated to physical and chemical measurements of volatiles, SO2, titratable and volatile acidity, oxygen and color, using Partial Least Squares Regression (PLS). In general, increased storage temperatures induced the largest changes in the wines; however, significant packaging temperature effects were found for some attributes as well - particularly wines stored in Bag-in-Boxes at 40°C showed significant increases in oxidized and vinegar aromas and yellow color. Volatile esters also decreased in these wines while increased levels of compounds generally associated with age or heat affected wine such as 1,1,6-Trimethyl-1,2-dihydronaphthalene (TDN) and furfuryl ether were found, consistent with previously reported chemical aging reactions. In summary, storing unoaked Chardonnay in different packages significantly changes the sensory and chemical properties depending on the storage temperature. After a storage period of three months, bottle storage with various closures (natural cork, synthetic cork and screw cap) changed the wine in a different way than Bag-in-Box storage.
