Reference: Impact on Tannat wines aroma produced by different yeast using three vinification systems
Key Statements

Abstract-

Vinifications were conducted using pure cultures of Saccharomyces cerevisiae, and mixed cultures by sequential inoculation of a Hanseniaspora vineae (T02/05F) and Hanseniaspora clermontiae (A10/82F), with a Saccharomyces cerevisiae conventional strain. The vinification systems applied to Tannat grapes were defined: semipilot, pilot and industrial scale. Fifty-one volatile compounds were identified in all the vinifications, sixteen of them were above the aroma threshold values and potentially contributed to the final sensory profiles. A sensory characterization of aroma was carried out using the projective mapping technique, with forty-eight consumers who made evaluation of the three vinifications. Multiple factorial analysis was used to compare the chemical and sensory data to find correlations. The results obtained from both methodologies were coincident, confirming the aromatic tendencies found in the different vinifications. Both studies demonstrated that wines obtained by semipilot scale was characterized by descriptors associated with “chemical” and “floral”; those from pilot vinification by the “spicy” descriptor; while industrial vinification produced wines described as “fruit” and “wood”.
