摘要：

Forty wines of Vitis vinifera cv. Pinot Noir from France, California, and the Pacific Northwest region of the United States were analyzed for 17 elements by atomic emission spectrometry. Intercorrelations among these elements and their relations to geographic origins were investigated by analyzing the elemental data with pattern recognition techniques. A distinct difference was found between the levels of aluminum in California and Pacific Northwest samples, while barium was the key element in distinguishing French Pinot Noirs from those produced in the United States. Differences in elemental concentrations due to intraregional and vintage variations were also identified. © 1979, American Chemical Society. All rights reserved.
