School for Viticulture and Enology

Grapevine Secondary Metabolites

This course is part of the programme:
Bachelor's programme in Viticulture and Enology (1st level)

Objectives and competences

The course is for those students, who desire to deepen their already conquered knowledge about the chemical composition of the wines and grapes, as well as about the new and modern analytical techniques in that area in the field of secondary metabolites with special emphasis on polyphenols

Prerequisites

Knowledge of general organic and anorganic chemistry, biochemistry and wine chemistry.

Content (Syllabus outline)

Lectures

  • The classification of the secondary metabolites: chemical

    structure and nomenclature the major secondary metabolites found in

    grapes and in wine: polyphenols, volatile phenols, nor-isoprenoids,

    terpenes, pyrazines, nitrogen and sulfur compounds.

  • The physiological role of the secondary metabolies in the vine:

    some secondary metabolites are phytoalexins and through that protect

    the plants against different diseases (Peronospora, Botrytis) or

    against the UV irradiation.

  • Changes in the secondary metabolites’ amounts during the grape

    ripening: the kinetics of the secondary metabolites biosynthesis

    during the grape maturation, which is an important information for

    making a decision about the harvest (polyphenol maturity, the amount

    of the nitrogen and aromatic compounds).

  • Evolution of the secondary metabolites during the vinification and

    wine aging: the chemistry of the secondary metabolites in wine.

  • The influence of the secondary metabolites on the organoleptic

    characteristics of the wine: the influence of the aromatic compounds,

    polyphenols, volatile phenols on the sensory characteristics of the

    red and white wines.

  • The nutritional value of the secondary metabolites in wine: the

    presentation of the recent and fresh research results from that area.

  • Analytical techniques of the secondary metabolites determination:

    the presentation of the new methods, which are more routine used (wine

    cellars) as well as with more profound, which are used in more modern

    and well equipped laboratories.

Intended learning outcomes

- profound knowledge of the secondary metabolites of grapes, must and wine

- profound knowledge and the latest findings in nutritional value of wines in conjunction with sekunarnimi metabolites (polyphenols and health)

- profound knowledge of simple and advanced analytics secondary metabolites of grapes, must and wine

- knowing and understanding of changes in the composition of secondary metabolites in grozju between dozoreavnje, during fermentation and aging of wines

- Independent study of topic from the field of secondary metabolites in grapes, must and wine
