How Do You Use An Alcohol Hydrometer?
An alcohol hydrometer is an instrument that you use to determine how much alcohol is in a volume of liquid. Hydrometers work by measuring the “specific gravity” of a liquid. Measuring the amount of alcohol in liquids is important if you make your own beer or wine. It also makes a good science project for kids. You can purchase or even make a hydrometer on your own to use for measuring, not only alcohol, but other types of solutions as well. Gather a sample of your unfermented liquid you want to test and pour it into a graduated cylinder. Fill the cylinder 2/3 of the way full. Insert your hydrometer into the cylinder. Spin it gently in your fingers to remove any air bubbles from the sides of the hydrometer or container. Lower yourself so that your eyes are parallel to the container. Read the measurement on the hydrometer to see where the top of the liquid hits it. This is your specific gravity measurement. Take the measurement of your alcoholic liquid after the fermentation process is c
