Starmerella bacillaris and Saccharomyces cerevisiae mixtures were used to ferment Barbera grape must.

The interactions between yeast strains were studied in mixed (co-inoculated and sequentially inoculated) fermentations.

HS-SPME-GC-MS was used to identify and semi-quantify 41 different volatile compounds.

Starm. bacillaris is more effective in modulating the aroma profiles of wines from mixed fermentations.

Mixed fermentations could be considered as a tool to enhance the aroma profile of Barbera.
