72487 - Chemical and Sensory Analyses of wine

Learning outcomes

At the end of the course, the student has the necessary knowledge to apply proper analytical methods aimed to the evaluation of winemaking, shelf life and critical evaluation of results in relationship with technological parameters of wine production.

Course contents

The class provides theoretical and practical activity with regard analytical methods used in winemaking and explanation for crucial parameters such as: sugars, alcohol, dry extract, ashes, pH, volatile and titratable acidity, sulfur dioxide, metals, color, polyphenols, nitrogen compounds. A brief description of laboratory safety instruction and applied statistics for data handling will be given. Practical activity will take place in laboratory.

Teaching methods

The course includes 6 CFU which will take place in classrooms and laboratories located inside the Campus of Cesena. The aim of theoretical classes is to provide students with information concerning the application of analytical protocols finalized to the analyses of enological products, define the proper time for performing analysis as well as the protocol to apply. Capability to perform a critical evaluation of results in relation to the enological product under evaluation. Practices will be focused on laboratory activities aimed to provide expertise in laboratory management and critical analysis of results. Student must provide by themselves a lab coat to wear during practical activity.

Assessment methods

The final evaluation includes a written test and an oral exam aimed to assess the achievement of the learning objectives and verify the knowledge of the candidates and their ability to apply the analytical protocols to everyday problems in winemaking processes. Following the written exam (duration 90 minutes) the candidates are requested to undertake an oral exam. Written exam and oral exam represent 60% and 40% of the final score, respectively. No support given by syllabus or books is allowed during the assessment. Enrollment must be accomplished through the ALMAESAMI site within the deadline. Cancellation must be done before the date of the exam.

Until the COVID-19 emergency, the exam will be manages through EOL and ZOOM platforms. In this view, it is necessary to have a computer (it is not possible to use tablets, smartphones or other mobile devices) with audio, microphone, webcam and the Zoom software already installed. During the exam test, the student will be required to keep the webcam active and share its PC's screen via Zoom [https://support.zoom.us/hc/en-us/articles/201362153-Sharing-your-screen]. Zoom Cloud meetings [https://zoom.us/support/download] must be installed and tested before handling. It is necessary to create an account with the university credentials (@ studio.unibo.it) following the University instructions ('How to take a written exam online with Zoom [https://www.unibo.it/it/servizi-e - opportunities / online-services / online-services-for-students-1 / lessons-and-exams-online] '); it is important to click on 'Sign in with SSO' (i.e. register with the University credentials) and enter the "unibo" .zoom.us domain. It is good to test the functioning of the webcam and microphone on the Zoom platform. For those who use a Mac computer, it is also necessary to check in advance how to allow sharing [https://support.apple.com/it-it/guide/mac-help/mh11848/mac] and registration [https: // support .apple.com / en-us / guide / mac-help / mchld6aa7d23 / mac] of the screen. In the event that the student is unable to meet these conditions, he must contact the teacher promptly, at least 15 days before the exam.

Teaching tools

Syllabus provided in electronic format (pdf) will be uploaded in the IOL system before the beginning of the classes. Books are available in the library to support students activity. Beside lectures, practical activity will be scheduled in the laboratory.
