What You Need to Know
A stuck fermentation is the term used in brewing beer or winemaking when the yeast becomes dormant before the fermentation has completed. Unlike an "arrested fermentation", where the winemaker intentionally stops fermentation, a stuck fermentation is an unintentional and unwanted occurrence that can lead to the wine being spoiled by bacteria and oxidation.
