Alcoholmeter floating in brandy. This instrument is a type of hydrometer that uses buoyancy to measure the alcoholic strength of liquids such as brandy, beer or wine. It consists of a weighted tube that floats vertically in the alcohol. The specific gravity (density) is determined by comparing the scale on the tube with the level at which it floats in the alcohol.
