Content (Syllabus outline)

- The detailed chemical composition of grapes, must and wine.

- Correction of must: sweetening, acidity adjustment, nutrition (“food”) for wine yeast (vitamins and nutrients), aeration, sulphiting, etc.

- Advantages and disadvantages of the use of oenological practices: when and why?

- Primary treatment of must; processing machinery; newer technology of white and red wines production: hiperreduction, micro-and macrooxygenation, use of inert gases in wine technology.

- Wine microbiology: taxonomy, physiology and biochemistry of wine yeast, lactic and acetic acid bacteria and mold, and their metabolites.

- Alcoholic and malolactic fermentation: kinetics; causes of stuck and/or sluggish fermentation.

- Starter cultures of yeast and lactic acid bacteria: their origin and the main types regarding to metabolism and optimal fermentation temperature, forms, methods of preparation and use of industrial starter cultures; measures to prevent infections.

- Biochemical and enzymatic processes in must and wine: creating bouquet and flavor of wine as a result of fermentation processes, natural enzymes and enzymes of microbiological origin (yeast-contaminants, bacteria and molds), use of glucanase, pectinase, maceration cocktails.

- Microbiological stabilization of wine, physico-chemical stabilization of wine: the stabilization of colloids, proteins, and wine stone (potassium hidrogen tartrate), fining and use of fining and other oenological agents and practices; modern techniques of filtration and bottling wine.

- Maturation and aging of wine, barrique technology.

- Deficiencies, faults, defects, and disease of the wine: the causes of their occurrence, prevention and elimination methods; methodology of physico-chemical instability of opened and bottled wine as well as microbiological changes, including the identification of spoilage microorganisms.

- Health and nutritional effects of moderate wine drinking: the most important antioxidants, their maintenance and function.

- Slovenian wine laws and regulations in relation to the world (OIV, EU, BATH).

- Marketing: plan, public relations, advertising, sales promotion.
- Physico-chemical analysis and microbiological control (HACCP); sensory analysis of wine.
