Definizione

A device used to determine the specific gravity of liquids. In winemaking, it is used to determine the alcohol concentration of wine. 1

Nota

A hydrometer measures the difference in gravity (density) between pure water and water with sugar dissolved in it by flotation. It is used to gauge the fermentation progress by measuring one aspect of it, attenuation. Attenuation is the conversion of sugar to ethanol by the yeast. 2
There are many variants of the hydrometer. Some have only one scale, some two and some three. The typical hydrometer measures three things: specific gravity (S.G.), potential alcohol (P.A.), and sugar. 3

Contesto

A hydrometer is an inexpensive yet essential piece of test equipment used by winemakers. It is generally made of blown glass, with a weighted, bulbous bottom and a long narrow stem.4
