 A review shows rotundone concentration in grapes at harvest and in commercial (C) or experimental (E) single-variety wine: [Geffroy, Olivier, Didier Kleiber, and Alban Jacques. „May peppery wines be the spice of life?

+"Application of the aroma extract dilution analysis (AEDA) on a distillate prepared from freshly squeezed juice of Dornfelder grapes revealed (3Z)-hex-3-enal and trans-4,5-epoxy-(2E)-dec-2-enal with the highest flavor dilution (FD) factors. In contrast, in the final Dornfelder wine prepared thereof, the highest FD factors were found for 2-phenylethyl acetate, 2-phenylethan-1-ol, and (E)-β-damascenone. However, for example, among others, (3Z)-hex-3-enal no longer appeared as an important odorant." \\
