Wine technology (159812)

Course coordinator

Course description

The module Wine Technology will provide students with modern knowledges relating to the technology of the production of white and red wines, with detailed description of all operations from the moment of grapes harvesting to wine bottling. Besides acquiring theoretical knowledge, students will take an active part in field work to get familiar with the operation of the machinery for harvesting, decanting, filtering and bottling of wines, and through the application of clarifiers and finishing procedures they will master the basics of chemical and physical analyses for checking wine stability.
