What does a hydrometer measure in brewing?

• A. The flavor of the beer
• B. The alcohol content of the beer
• C. The specific gravity of the liquid
• D. The temperature of the wort

Answer: (C)

The hydrometer is an essential tool in brewing that measures the specific gravity of a liquid, which is a crucial factor in determining the brewing process's efficiency and the potential alcohol content of the finished beer. Specific gravity refers to the ratio of the density of the liquid to the density of water and is influenced by the concentration of sugars in the wort prior to fermentation. By measuring specific gravity before and after fermentation, brewers can calculate the amount of sugars converted to alcohol, thus determining the potential alcohol content. This measurement provides valuable insights into the fermentation process and helps brewers monitor the health and progress of yeast activity. The other options do not accurately describe what a hydrometer does. While flavor is subjective and influenced by various ingredients and processes, a hydrometer has no capability to assess flavor profiles. Alcohol content can be indirectly inferred through specific gravity measurements, but it is not the direct measurement provided by the hydrometer. Additionally, temperature is measured with a thermometer, not a hydrometer, making the specific gravity measurement the primary function of this instrument in brewing.
