The objective of this study was to extract, isolate and analyze the antioxidant, resveratrol from various red, rosé and white wines.  Three different growing locations were selected for this study.  The three vineyards include US west coast (Oregon/Washington), US east coast (New York, Finger Lakes region) and France.  Merlot, Rosé and Chardonnay from each vineyard location were selected as the wines for analysis and comparison.  The extraction and quantification of resveratrol was conducted in order to compare the amount of this antioxidant found in the different red, rosé and white wines. In order to extract resveratrol liquid-liquid phase techniques were implemented. The concentration of the antioxidant was quantified using ultraviolet spectroscopy at a wavelength of 310 nm. High Performance Liquid Chromatography was also used to isolate and identify the active ingredient from each wine after extraction. The analysis of the data collected from this study will suggest which type of wine contained the most resveratrol.<br/> <br/>
