Prerequisites: In order to successfully attend the course, it is recommended that the student has the skills and knowledge gained from courses in mathematics and physics. It is also desirable the ability to use computer tools such as excel.
Target skills and knowledge: The aim of course is to provide a knowledge on the working and on the selection and design criteria of enological machinery and plants.
Examination methods: Written test
Assessment criteria: The skill evaluation of the student will be based on the examination of: the understanding of the working of machinery and equipment in the enological sector; the acquisition of the criteria for selection of the enological machinery; the ability to apply the design criteria of the enological plants.
