An analytical profile of a total of 49 samples of 1970 and 1971 vintage Rhine and Moselle German white wine is presented. The data include atomic absorption analysis for the elements K, Na, Mg, Ca, Fe, Cu, and Zn; gas‐liquid chromatographic analysis for methanol, ethyl acetate, n‐propyl alcohol, iso‐butyl alcohol, and iso‐amyl alcohol; the traditional specific gravity determination for ethanol; and the determinations for total acids, solids, and ash. For each of the parameters determined the range, mean and standard deviation is given. A comparison of the data for the 1970 and 1971 vintage years and the Rhine and Moselle wine regions is included. The conclusion is drawn that the data are insufficient to determine distinguishing and identifying characteristics of either vintage year or wine region.
