Alcohol Contraction or Dilatation with temperature
During a temperature increase, volume of alcohols expands or conversely, during a temperature decrease, the volume contracts. The higher the alcohol content, the more pronounced this phenomenon becomes.
In the field of spirits, during production, for inventory management and bulk transactions, the measured volume can vary significantly due to temperature fluctuations. Therefore, it is essential to convert the measured volumes to 20°C for accuracy.
So how to calculate the volume at 20°C ?
