Course objectives |
The aim of the course is to teach students about basic concepts and technologies used in the production of alcoholic beverages, explain them the differences in the types of alcoholic beverages based on the used raw material and production method, and to transfer them the knowledge necessary for planning and managing the technological process of alcoholic beverages production. |
Learning outcomes expected at the level of the course (4 to 10 learning outcomes) |
Students will on successful completion of the course be able to:
- define and group alchocolic beverages based on the origin of raw materials and applied production technology,
- prepare the basic raw material for the production of alcoholic beverages,
- describe the basic steps in the manufacturing process for different beverages,
- define basic chemical, physical and sensory parametres used in quality testing of alcoholic beverages,
- apply the knowledge in the production process. |
