Résumé
The Domaine du Rieu Frais is located near Nyons, in the heart of the Baronnies Provençales.The vineyard is conducted organically and must therefore deal with all the problems that this implies.During the 2021 vintage, pathological pressure was limited and the quality of the harvest wasexceptional. This was seen during the vinification process where yields were much higher thanexpected, leading to logistical issues concerning cellar management. Few problems during thevinification appeared during this vintage, with the exception of the lack of maturity of the Syrahgrapes, which required chaptalization for the first time in 8 years.The experiment set up allowed us to see the impact of removing SO2 during vinification on theorganoleptic profile of Gamay rosé wines. No statistical difference could be observed in the triangularanalysis. However, during the quantitative descriptive analysis, it was observed that the non-sulphitedmodality had a more intense nose than the sulphited control, and there were more floral, amylic andevolved fruit notes in the mouth. Micro-vinifications must be carried out on several vintages in orderto eliminate the various biases and confirm these results.
