A hydrometer is an instrument that measures the specific gravity (relative density) of liquids—the ratio of the density of the liquid to the density of water. For wine and beer making, a simple hydrometer is used to determine the amount of alcohol in the brew in order to decide when it is ready to be placed in bottles.
