Rootstock and vineyard floor management influence on 'Cabernet Sauvignon' grape yeast assimilable nitrogen (YAN)

► Grape nitrogen (N) compounds are essential for a healthy fermentation. ► This study explored how two rootstocks (110R and 420A) and three vineyard floor management techniques affected 'Cabernet Sauvignon' grape N content and composition. ► Findings suggest that vineyard managers can utilise barley and mowing (no-tillage) without impacting grape quality indicating compounds.
