Description

Wine is an alcoholic beverage produced through the partial or total fermentation of grapes. Wine is characterized by color: white, pink or rose, and red. Red wine available in Albanian market was characterized for physicochemical and rheological properties. In the first phase, the physicochemical parameters were determined: density, total acidity, volatile acids, content of the alcohol, reduced sugars, free SO2, total SO2, pH and electric conductivity. In the second phase of the study, density and dynamic viscosity were experimentally determined as a function of temperature from 5 to 40°C. Kinematic viscosity and fluidity were determined according to the definitions. The dynamic viscosity of wine was represented as a function of temperature by using two and multi-constant proposed mathematical models.

Modeling the effect of temperature on rheological properties of red wine
