Rotundone in Gruner Veltliner and skin contact impact
by Richard B.
It is also interesting to mention that rotundone, as you mentioned in your article What does Make Peppery Wines Peppery? is variety specific, and is present in the white skin of Gruner Veltliner.
Wine tasters appreciate this varietal characteristic in Gruner Veltliner "the Groovy white peppery wine" as a white pepper taste (rotundone is known to be present in black and white peppercorn).
It is still curious and unexplained that rotundone concentration is kept in winemaking following skin contact since rotundone presence is mainly located in grape skins. White Gruner Veltliner elaboration has very short to no skin contact !?...
