Installed successfully in over 100 malt whiskey stills over the last 15 years, the instrument described in the article has proven to be the ideal instrument for online alcohol concentration measurement. The instrument provides accurate and consistent process control points to ensure the quality of the spirit. There is a reduction in the labour cost as the spirit safe does not need tending.


With the current cost of energy it is important that the stills are switched off before any benefits of spirit collection are out-weighed by the cost of the energy used to produce it. The instrument can be used in conjunction with a control system to ensure consistent and efficient operation of both spirit and wash stills. The system uses high frequency ultrasonics and temperature to calculate the concentration of the liquid.

 Take note

  • In whiskey production, it is crucial that spirit cuts are done at the correct strength.
  • An instrument has been developed that provides accurate and consistent process control points to ensure the quality of the spirit.
  • The instrument can be used in conjunction with a control system to ensure efficient operation of spirit and wash stills.
