Sousa, Raul Bruno de; Canas, Sara; Belchior, A. Pedro; Mateus, Ana M.; Spranger, Maria IsabelAn essay was carried out under model conditions, simulating the natural ageing of brandies in 250dm3 wooden barrels, to study the kinetics of impregnation/evaporation of brandy and the release of phenolic compounds from wood into brandy. The influence of wood botanical species (Limousin oak and portuguese chestnut), toasting level (light and strong)and ageing time (0, 42 and 250 days) was investigated. In paral...
Modelização do tratamento térmico de madeira de carvalho português (Quercus Pyr...
Sousa, Raul Bruno de; Canas, Sara; Grazina, Nelson; Belchior, A. Pedro; Spranger, Maria IsabelThe heat treatment is of primary significance for the barrel quality. In the last fifteen years many papers have been focused on the effects of heat treatment on the phenolic composition of French and American oak woods, but the oak species grown in Portugal traditionally used in portuguese cooperage have never been studied. In this study we characterised the toasting levels with temperature and time by modelli...
