White and Rosé Programmes Software
Thanks to the Oenoterris Fleur and Oenoterris® Aroma nutritional biostimulants, the White and Rosé Programmes promote the synthesis of thiol precursors by stengthening the plant’s resistance to stress and by limiting asynchrony issues. The figure opposite illustrates the increase in these levels and shows that the median and mean concentrations of cysteine precursors observed in Sauvignon Blanc must are globally higher if these Programmes are applied.
Higher medians and averages of the three molecules (3SH, 3SHA and 4SMP) were found in Sauvignon Blanc wines that followed the Oenoterris® White Programme, illustrating a good conversion of precursor potential.
These results are confirmed by sensory analysis. The wines that were tasted have an intense aromatic profile that is fresher and less bitter , and which meets the aromatic profile goal of the White Programme.
