What is the term for the residual sugar left in beer after fermentation?

1. Final Gravity

2. Alcohol By Volume

3. Original Gravity

4. Hop Residual

The correct answer is: Final Gravity

Final Gravity is the correct term for the residual sugar left in beer after fermentation. It represents the specific gravity of the beer once fermentation has concluded, measuring the density of the liquid and indicating how much sugar remains compared to pure water. This final measurement helps to determine the sweetness of the beer, as higher levels of residual sugar lead to a sweeter taste profile. In brewing, this value is significant because it not only informs brewers about the fermentation process and the yeast's effectiveness at converting sugars into alcohol but also affects the beer's overall flavor, mouthfeel, and body. Knowing the final gravity allows brewers to balance their recipes and achieve the desired taste and texture. The other terms listed refer to different aspects of the brewing process. Alcohol By Volume indicates the percentage of alcohol in the finished beer. Original Gravity measures the density of the wort before fermentation begins, helping to predict the potential alcohol content. Hop Residual does not refer to sugar in beer but rather could imply any leftover compounds from hops used in brewing, which can influence bitterness and aroma but does not relate to residual sugars.
