Continuous fed-batch strategy decreases acetic acid production and increases volatile ester formation in wines under high-gravity fermentation

OENO One, 2023
High sugar fermentation elevates acetic acid levels in wines, which can be avoided by applying the continuous fed-batch strategy. In this study, yeast gene expressions and wine volatile compounds were evaluated by quantitative real-time PCR (RT-qPCR ...
