Study : characterisation of different plots according to their sensitivity to oxygen,measured on the must using a potentiometric titration. Depending on this sensitivity, a technicalitinerary is set up to improve the extraction of tannins and increase the degree of polymerization, which will allow the wines a better resistance to oxygen.Laboratory : - Chemical analysis of grapes, juice, fermenters, wine - Operating analytical instrumentation according to standard… Show more Study : characterisation of different plots according to their sensitivity to oxygen,measured on the must using a potentiometric titration.
