Post‐veraison restriction of phloem import into Riesling ( Vitis vinifera L.) berries induces transient and stable changes to fermentation‐derived and varietal wine volatiles

Background and Aims The climate-change driven uncoupling of grape (Vitis vinifera L.) berry ‘sugar-ripeness’ and ‘flavour-ripeness’ necessitates an improved understanding of the sugar/flavour nexus. Methods and Results Analysis of grape metabolites and wine volatiles derived from Riesling berries of peduncle-girdled and Control bunches over the course of 30 days provided time-dependent insights into changes to grape and wine composition...
