20402440 - PRINCIPI DI ENOLOGIA, ENOGRAFIA E TECNICHE DI DEGUSTAZIONE

The course has among its aims to provide the basic principles of wine and elements of technological organization of the winery and the cellar. In addition, thecourse aims to give students a knowledge framework of the national and worldproduction of wines and sparkling wines, and the tasting of the theory.

Main indexes for determining the right harvest-time. Harvest and methods for picking.
Chemical composition of must. Main constituents.
The Transformation of must into wine: Fermentation
Outline of oenological microbiology. Oenological yeasts: Saccharomyces cerevisiae and other strains of oenological interest. Basic elements of taxonomy, reproductive cycle, cell function and structure.
Alcoholic fermentation: glycolisis, from pyruvic acid to ehtyl alcohol, glyceropyruvic fermentation.
Malolactic fermentation. Lactic bacteria and their metabolism. Maloalcoholic fermentation.
Chemical composition of wine. Main constituents.
Monitoring fermentation processes during wine making. Fermentation stops, causes and prevention.

Vinification. White wine vinification, red wine vinification and special types of vinification.
White wine vinification: distinctive features. Quality criteria and oenological objectives.
Techniques for must extraction, skin maceration, cryomaceration, preventing must oxidation, fining and cleaning of the musts.
Managing the fermentation process (adding yeasts, monitoring temperatures and the kinetics of fermentation). Red wine vinification: an outline. Mechanical operations on grapes.
Managing alcoholic fermentation. Managing maceration and extractive techniques. Racking off and pressing. Managing malolactic fermentation.
Special vinifications: rosé wines, raisin wines, botrytized wines, wine under flor, dessert wines.
