Characteristics and production of the main classes of malts used in brewing. Milling of malt and wort production (mashing). Water quality (source, ionic composition, treatments). Principal mashing methods and mashing biochemistry (starch conversion, proteolysis..). Hops: processing and forms used in brewing, specifications and introductory hop chemistry. Wort boiling, clarification and cooling. Brewing yeast management and fermentation. Brewing yeast taxonomy and biochemistry. Biological and chemical processes that contribute to the maturation of beer. Formation of non-biological hazes and stabilisation against non-biological haze. Clarification and filtration. Bottling. Sensory analysis of beer. SPIRITS - Distillation principles. The properties of ethanol-water mixture. Batch and continuous distillation. Processing of grappa, Cognac, brandy, whisky, rum, gin and vodka.

Assessment methods and Criteria
The examination consists of a written test aimed at ascertaining the student's knowledge of the theoretical and applicative aspects of beer technology and distillates. The written test consists of about 30 closed-ended questions. In order to take advantage of the facilities provided for the exam, DSA students must first notify the Office (www.unimi.it/studenti/serviziodisabiliedsa.htm) of their situation. Students enrolled in an examination call and who no longer wish to take the exam are required to promptly inform the teacher. In the event of non-compliance, they will not be able to present themselves at the next appeal. The examination method is considered effective for achieving an assessment of skills acquired by the student in the context of the technologies of alcoholic beverages and spirits, taking into account the topics covered in the lectures.
