Hydrometer was an instrument used to measure the specific gravity (relative density) of liquids; that is, the ratio of the density of the liquid to the density of water. A hydrometer is usually made of glass and consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright. In an age where wine and beer was made as water was unsafe, the Hydrometer was integral " beer making process that allows homebrewers to adjust and predict the integrity of their recipe by providing accurate readings of the beer's sugar level as well as its specific gravity."
