Brewing wine with Specific Gravity hydrometer: Comments by Gert Strand

HYDROMETER CHOICES

There are two types of hydrometers, the Specific Gravity Scale and the Oechsle Scale (named for Ferdinand Oechsle). Each has a different measurement scale.
Generally, people familiar with the measurement systems in the United States and the United Kingdom refer to the Specific Gravity Scale. Others may prefer the Oechsle Scale.
We have created two entire sets of instructions for these hydrometers.

Measure the must before fermentation begins, make a note of the hydrometer (with Oechslescale) reading.

Measure again when bottling.
The reading divided by 8 = the % alcohol by volume.
