Wine distillates, fruit wines and other products of the vitiviniculture origin

Objectives and competences

Students learn the technical principles of processing fruit and grapes into various products that can be an important complement to processing grapes into wine on the farm. They learn about technologies for the production of wine spirit from wine, yeast and pomace, technologies for the production of grapes into juice, the production of beverages based on grape juice and wine, the production of fruit wines, the production of raisins and the processing of grape seeds into oil. In addition to the technologies required for the characteristics of the input raw material, the pre-treatment of the raw material and the production equipment, they will also learn about the physicochemical characteristics of these products, the control parameters, the legal requirements, the legal product classifications, the labeling, the storage, the packaging methods and the sensory characteristics of the products on the market.

Prerequisites

Not required.
The object is also connected to other content items from the field of viticulture, enology, microbiology and wine chemistry.

Content

LECTURES

During lectures, students will be taught about various technologies (history + latest trends) in:

Technology of production of distillates based on grapes, pomace, yeast, wine.
Technology of production and processing of grape juice
Technologies of production of wine or grape juice based beverages
Technologies for the production of dealholized wines
Technology for the production of raisins
Technology for the production of grape seed oil
Technologies for the production of fruit wine in the EU and elsewhere in the world.

Students will also learn about related national and EU legislation, product classification, labeling, packaging methods, potential product defects and diseases, and the expected sensory characteristics of the products of selected technologies.

OPENINGS

In the exercises students will learn practically:
- Different types of spirits, odor and taste defects of spirits, and tasting of spirits. They also perform laboratory analyses of different types of spirits.
- Various fruit wines, defects and diseases of fruit wines, their taste and sensory characteristics, also perform laboratory analysis of various fruit wines.
- Basic quality analyzes of grape juice and grape concentrate
- Get acquainted with various beverages based on wine and grape juice, dealcoholized wines - their chemical and sensory properties.

In the practical exercises, students learn about various technologies for the production of distillates based on grapes and wine, the production of fruit wines, grape juice, and grape concentrate, as well as technologies for the production of grape seed oil.
