ResumoThe objectives of this study were to evaluate the potential of gabiroba Campomanesia pubescens (DC) O. Berg in the production of a beverage fermented using selected and wild yeasts from indigenous fermentation, analyze the volatile compounds profile present during the process of fermentation, and evaluate the sensory quality of the final beverage produced. Throughout the process of fermentation, when Saccharomyces cerevisiae UFLA CA 1162 was inoculated, there were stable viable populations around 9 log cells ml−1. During indigenous fermentation, yeast population increased from 3.7 log CFU ml−1 to 8.1 log CFU ml−1 after 14 days. The diversity and dynamics of the yeast population during indigenous fermentation observed by PFGE analysis showed five different karyotyping profiles in the first days of fermentation. After the seventh day, there was a higher frequency of a similar S. cerevisiae profile. The yeast non-Saccharomyces were identified by sequencing of the ITS region as Candida quercitrusa and Issatchenkia terricola. Inoculated fermentations yielded a higher amount of alcohol than indigenous ones, indicating the efficiency of selected strains. There was also a greater concentration of higher alcohols, which are usually responsible for the flavor found in alcoholic beverages. Based on the characteristics of the pulp and acceptance in the sensory analysis, gabiroba fruits showed good potential for use in the production of fermented beverage.
