Measurement of Whiskey by DSC

Whiskey was sealed in a hermetic cell and measured by DSC. The exothermic peak at -74.2°C is due to crystallization. The peak at -65.9°C shows the melting of ethanol, -49.8°C the eutectic point of ethanol and water, and -25.6°C the melting of water. The height of the eutectic peak varies depending on the storage period of the malt.
