Abstract

The fermented beverage industry is always pursuing alternatives to make products that delight consumers with special or unique characteristics. The identification and improvement of new yeast strains emerge as an opportunity; however, wild strains usually have a limitation in maltose fermentation and/or off-flavors production. Here we report the production of a Blond-style ale beer using a bioethanol isolated strain (LBGA-287) with flavor complexity approved in sensorial panels. LBGA-287 also showed an increase in maltose consumption, growth and fermentation rates when compared to the commercial yeast. Using qPCR analysis, genes related to the (i) efficiency of fermentation (ii) production of aromas/off-flavors, and (iii) metabolization of carbohydrates were found as differentially expressed in the isolated strains when compared to industrial yeast. This suggests that LBGA-287 could have an important impact on beer production, improving brewing efficiency, quality and diversity of this beverage, and most importantly satisfying the final consumer.
