Influence of Fermentation Temperature and <i>Metschnikowia pulcherrima/Saccharomyces cerevisiae</i> Multi-Starter Cultures on the Volatile Compounds of Lugana Wine.

ABSTRACT: Low fermentation temperatures are a crucial aspect of winemaking, influencing yeast metabolism, process efficiency, and aroma retention. However, it is a significant source of energy consumption. Here, we investigated the effect of high (20 °C ± 1 °C) and low (16 °C ± 1 °C) temperatures combined with multi-starter fermentations with Metschnikowia pulcherrima (Level² Flavia and Level² Initia) and Saccharomyces cerevisiae (EC 1118 and Zymaflore X5) strains on the aromatic profile of Lugana wine. Sequential inoculation at 20 °C shortened fermentation by five days compared to 16 °C, lowering energy consumption for cooling. Significant differences in key aromatic compound classes were observed between the two temperature trials. Wines fermented at 20 °C exhib
