A maceration period can particularly intensify this aroma. Rieslings from more substantial soils - such as, for instance in the Pfalz, in the upper Rheingau, in Wachau and Alsace - exhibit this intensive smell-of-apricots characteristic very distinctly. Surprisingly, apricot aromas arc still perceivable when the Riesling grapes are affected by Botrytis cinerea.
