THE HYDROMETER Introduction
The hydrometer is a floating weight used to
determine how many grammes one litre of must
(unfermented grape juice) or wine weighs.
There are two different sets of scales:
1. Specific Gravity(S G) – most used by US/UK
2. Oechsle Scale– named after Ferdinand Oechsle of Pforzheim, Germany
The hydrometer is winemaking’s most important instrument.
To illustrate, in Germany, the entire legislation regarding winemaking is based on the hydrometer! And German winemaking legislation is
the most stringent in the world.
Winemaking without a hydrometer is like driving a car without a steering wheel – there’s a strong chance of not getting to the destination. It is the only instrument necessary for the winemaker.
Professional winemaking would be impossible without it.
