When brewing beer, the fermentation broth is at least in the post-ripening stage.

Does the subject want to ask, "How long does it take at least for the fermentation broth to mature in beer brewing?" 1 to 2 weeks. The post-ripening stage is an important stage of beer fermentation, and the yeast in the fermentation broth will continue to consume the remaining fermentable sugar and convert it into alcohol and carbon dioxide. In the post-ripening stage, the fermentation broth needs to be preserved at low temperature to prevent the yeast from continuing to ferment and producing too much carbon dioxide, which takes 1 to 2 weeks.
