Learning objectives
Unit 1: To know the main unit operations used in Oenology technologies in terms of phenomenology, balance of matter and energy and kinetic energy. Knowing the specific language, relationships and mathematical models useful for solving numerical problems for the control of operations.
Unit 2: Knowledge of grape structure, tissues and composition. Understand the vinification conditions suitable to the grape composition and their effect on the wine properties. Learning the wine making path from grape to young wine as well as the chemical, microbial and technological factors affecting it.
Expected learning outcomes
Unit 1: Improvement of the ability to calculate and solve problems in the unit operations treated. Schematization of the main machines used in the industry and of the operating conditions of the treatments. Acquisition of linguistic and technical terms.
Unit 2: Being able to assess suitable conditions for grape must extraction based on the grape characteristics, available technology and sensory properties of wine to be produce. Student will be able to manage the fermentation yeast as well as the vinification process.
