Issue Date: | 2019 | Source: | Beverages (Basel), 5(60), p. 1-8 | Abstract: | The Boltzmann equation is applied to fit data of volume loss for evaporation (in %) during spirit ageing in northern white oak (Quercus Alba) standard barrels of 205 L (+/− 10 L) using a temperature and humidity controlled cellar. The Boltzmann equation satisfactory fitted to the experimental data of the volume loss against temperature at constant humidity. Two parameters of the Boltzmann equation showed a linear dependency on the relative humidity of the air, while the other two parameters exhibited a constant value independently of the air humidity. The found empirical mathematical model can be used to calculate the volume loss for evaporation of spirits (40% v/v of ethanol) during ageing in terms of relative humidity (range: 40%–95%) and temperature (range: 10–30 °C) with significant accuracy. | Notes: | The authors would like to thank VLIR-UOS (Flemish Interuniversity Council for University Development Cooperation) project between Belgium and Cuba for providing funding and granting the support of the current and future studies. | Keywords: | angel’s share; Boltzmann equation; ageing; volume loss; spirits | Document URI: | http://hdl.handle.net/1942/29810 | Link to publication/dataset: | https://www.mdpi.com/2306-5710/5/4/60 | ISSN: | 2306-5710 | e-ISSN: | 2306-5710 | DOI: | 10.3390/beverages5040060 | Rights: | 2019 by the authors.
