| Analisi del vino e vini speciali
(objectives)
The course is based on two integrated parts wich, respectively, are referred to the learning notions of oenological analysis, and to the knowledge of the oenological procedures known as 'special vinifications'. The firstone didactic block is addressed to give to the students basic knowledges, as theoretical and practical way, on the main analytical determinations, based on official and legal protocols, for principal enological measurements on winegrapes, musts and wines. Otherwise, the secondone modulus is aimed at treating vinifications of dehydrated/withered winegrapes (for both sweet or dry wines production); botrytized wines, fortified and sparkling wine production. During the course and at the end of it, the student will acquire: 1) knowledge and understanding; 2) applying knowledge and understanding; 3) making judgements; 4) communication skills; 5) communication skills

(syllabus)
1. Basic and legal analytical methods to determine the main quality attributes in grape, musts and wines and to measure oenological parameters
1.1. Principles of spectrophotometric techniques based on enzymatic reactions and colorimetric assays
1.2. Principles of main analytical procedures based on chromatographic and liquid chromatographic techniques
2 Sweet, reinforced and dry wines obtained from withered grapes
2.1. Management of vineyards aimed at producing wines from dehydrates grapes
2.2. Technological aspects involved in grape drying and management of the grape dehydration processes
2.3. Biochemical and physiological aspects characterizing the grape dehydration processes
2.4. Modifications of the secondary metabolites fraction occuring along the grape dehydration process: definition of volatile compounds and of phenolic fraction
4. Wines derived from botrytized grapes: Tokaj and Sauternes, the botrytized wines
5. Management and criticisms of vinification processes addressed to produce special wines coming from withered grapes
5.1. The recovery of the aromatic fraction and of the wine color
5.2. The role of the yeasts
6. Dry wines derived from withered grapes: the case of Amarone wine, the 'Governo all'uso Toscano' wines, and the reinforced wines
7. Principles of fortified wines: Pedro Ximenez (Jerez), Porto, and Marsala wines
8. The sparkling wines production: Champenois method and Charmat-Martinotti method
