Harris Organic Distillery
We have the best organic distillery in Perth
Distillery History
Established in 1999, the Harris Organic vineyard has been nurtured by hand—every step from spring budburst to winter pruning is carried out with care by Duncan.
Managed under organic viticulture principles, no synthetic fertilisers, herbicides, or pesticides are used in the vineyard.
The organically grown grapes are crafted into a unique wine, which is then transferred to a wood-fired pot still for distillation.
Alcohol hydrometer temperature correction calculator
Below is the alcohol temperature correction calculator I use to calculate spirit strength at 20 degree celsius. Feel free to use it yourself.
Convert observed alcohol (% v/v) at measured temperature to 20°C.

A bit about how to calculate the strength of alcohol and alcohol temperature correction.
What is Alcoholic Strength?
Calculating the strength of alcohol involves measuring both the specific gravity and the temperature of a sample.
Alcohol hydrometer temperature correction
A hydrometer is used to determine the apparent strength, which is the density of the liquid relative to water.
In practice, the hydrometer reading is taken at a known temperature, but because alcohol expands and contracts with temperature, this reading alone does not give the true alcohol content.
To obtain accurate results, a thermometer is used alongside the hydrometer. The sample’s temperature is recorded and compared to
the calibration temperature of the hydrometer (usually 20°C).
Since alcohol strength varies with temperature, the reading must
be corrected using temperature compensation tables.
This is where the Practical Alcohol Strength Tables Volume 1 become essential,
offering corrections for observed strength and temperature across a wide range of values.
The alcohol temperature correction tables used here are published by the OIML (Organisation Internationale de Métrologie Légale) allow users to determine the true alcohol
content in %ABV by interpolation. Volume 1 is specifically designed for mixtures of ethanol and water, making it suitable for
use in distilleries and laboratories.
By matching the observed hydrometer reading with the corresponding temperature, one can
accurately determine the corrected strength—critical for compliance with excise regulations, product labelling, and quality control.
