Specific heat

Specific heat is an indicator of the amount of heat required to raise the temperature of 1 kg of a given substance by 1°C, and it plays an important role in understanding the thermal properties of a material. In sake, specific heat is one of the factors that influence temperature control and the fermentation process. For example, a substance with a high specific heat requires a large amount of heat to change its temperature, so its temperature tends to fluctuate less. By making use of this property, brewers can keep temperatures stable during the sake brewing process, which contributes to better quality.
