Alsace grape

Research by Tominaga et al. (2000) (Table 7.8) showed that the thiols identified in Sauvignon Blanc wines also contributed to the aroma of several Alsace grape varieties, as well as Colombard, Manseng, and botrytized Semilion. 

SNIF-NMR and/or IRMS techniques were often combined with trace element analyses (ICP-MS, ICP-OES, FAAS, ETAAS, GFFA) and chemometrics for the geographical characterization of wines. In a relatively old paper, Day et ah (1995) analyzed 165 grape samples collected in 1990 in four different production areas of France (Alsace, Beaujolais, Burgundy, and the Loire Valley). The combined use of isotopic and trace element data allowed an excellent classification of wine samples corresponding to... 

Another style of botrytized sweet wine from France involves the category of "Selection de Grains Nobles" (SGN). This legal definition was introduced in 1984 in Alsace, but similar wines are produced also in the Loire valley from grapes of different varieties and sugar contents (Table 6.2).
