This study describes the first report of application of Metschnikowia pulcherrima combined with Saccharomyces cerevisiae to ferment plum wine. Variable factors studied include inoculum ratio (M. pulcherrima: S. cerevisiae = 10:1, 1:1, and 1:10), as well as simultaneous versus sequential inoculation, with tested trials spanning 10:1sim, 1:1sim, 1:10sim, 10:1seq, 1:1seq, and 1:10seq, respectively. The yeast growth kinetics, physicochemical characteristics, organic acids, aroma profiles, and sensory evaluation were investigated. During fermentation, M. pulcherrima growth was inhibited by S. cerevisiae. Compared to each simultaneous analog, sequential fermentation which was inoculated with the same yeast ratio consumed less sugar and produced lower ethanol content. Organic acids in each sample varied with the use of different inoculation strategies. A total of 48 aroma compounds were quantified, and 1:1seq sample was observed to be abundant in esters and terpenes but relatively low in higher alcohols, fatty acids, and phenols. Sensory evaluation of the...
