The wine question of the day
What is the name of the device used to measure the specific gravity or density of liquids and which is also used to determine the alcohol concentration in wine?
Your answer:
Sorry, that's not the right answer!
Correct answer is: areometer
Excellent! that is the right answer.
areometer
Physical measuring instrument (also sinker, hydrometer, outdated gleucometer) for determining the specific gravity or relative density of liquids. In contrast, a pycnometer is used to determine the density of solids or liquids by weighing, and an aerometer is used for gases. The name areometer is derived from the Greek "araios" (thin) and "métron" (measure, scale), hydrometer from "hýdor" (water).
Principle and inventor
The measurement of alcohol concentration, which is ultimately based on the principle of the lowering spindle described by Archimedes (287-212 BC), was already known in antiquity. Archimedes' principle states...
