Abstract:
In this study, two different white wines were produced from Chardonnay grapes grown in Tekirdag/Sarkoy using traditional method (TM) and sur lie&batonnage (lees contact and stirring) technique. The composition, aroma and sensory properties of the white wines produced were investigated. Liquid-liquid extraction and GC-MS technique were used in analyzing aroma compounds, and flavor and odor profile analysis method was used in sensory analysis. In the wine made with TM, 45 aroma compounds were identified and the total amount was 210 mg/L. In the wine made with sur lie&batonnage, 54 aroma compounds were identified and the total amount was found as 209 mg/L. It has been found that the wine made with sur lie&batonnage contained barrel compounds and also found in higher amounts of esters, aldehydes/ketones, lactones and volatile phenols. It was determined that the sensory characteristics of the sur lie&batonnage wine are honey, spices, dried fruit, vanilla and butter/creamy. TM wine was characterized by citrus, floral and tree fruites. It has been determined that the wine made with sur lie&batonnage was sweeter, bodied and more persistent on the palate than the wine made with TM. As a result, the wine made with sur lie&batonnage was more appreciated and found better quality.
