Distilling & Brewing Advice: Alcoholometer or Density Hydrometer

Alcoholometers are used to read the alcohol content of pure distilled spirits.

Alcoholometers should only be used in pure, distilled spirits when determining the alcohol % or proof of the spirit. Alcoholometers are calibrated to the density of pure ethanol and won't sink as deep when water is added to the mixture. All Alcoholometers which are manufactured according to AS2371 are supplied with a Certificate of Conformity for Tax purposes.

Density hydrometers can be used to determine potential alcohol % during pre-fermentation and post-fermentation.

These particular hydrometers are calibrated to the density of water and will float at 1.000. More sugar within the mixture makes the hydrometer harder to sink therefore giving you a reading. Hydrometers listed in the following link are supplied with a Certificate of Conformity for Tax purposes.
