The substances were 3-isobutyl-2-methoxypyrazine, three norisoprenoid-ketones, free terpenols and the alcohols with six carbon atoms. Wines made from the 1993 harvest contained more 3-isobutyl-2-methoxypyrazine and fewer norisoprenoids-ketones because of the cooler climatic conditions in that year. The wine of clone 182 had higher levels of 3-isobutyl-2-methoxypyrazine for the two harvests. ER -
