  • Training structure

    Faculty of Science

  • Language(s) of instruction

    French

Presentation

The oenologist accompanies and supervises wine production in cooperatives and winegrowing
operations. They can also work in laboratories and institutes, in
research, consultancy and innovation roles that are particularly decisive in the face of the new challenges facing this profession
.
In the wine industry, they are the scientific experts.
The L3 DNO preparatory course is designed for students wishing to become oenologists, with a particular
interest in the sciences.

Objectives

The aim of the DNO preparatory course is to provide a scientific refresher for students from
different backgrounds, through the acquisition of solid theoretical general knowledge and
essential to the profession of oenologist, mainly in chemistry, but also in biology.
It also aims to awaken the scientific spirit, develop rigor and critical thinking,
put students in a position to solve new problems and develop
interpersonal skills.

Know-how and skills

This pathway in the Chemistry field offers students the opportunity to acquire :
specific disciplinary and technical skills (mobilizing concepts to analyze and solve
problems in organic and inorganic chemistry, applied thermodynamics and
analytical chemistry; adopting a multidisciplinary approach; mastering basic knowledge of biology
molecular ; independently design and carry out an experimental procedure including
chemical and biological analysis methods, optimizing and validating the analysis techniques learned,
understand and interpret experimental results using the relevant scientific literature
to the problem, use statistical tools adapted to biology),
-professional (acquire organizational skills to manage projects,
defining objectives and context, developing the notion of responsibility in the service of a project,
self-evaluation, analyzing viticultural systems, knowledge of major issues related to
food science, leading a supervised professional project),
- cross-disciplinary and linguistic (analyze and synthesize data with a view to
their exploitation; using different tools and information and
communication technologies to process and produce information; knowing how to communicate in
English)
- relational (learning to cooperate on projects, identifying resources and
limitations within a group, taking a step back from a situation, rethinking the way
you interact to promote cohesion)

Organization

Internships, tutored projects

This theoretical training is supplemented in semester 6 by a compulsory internship in a company
or a wine-related university laboratory.
Some courses include collaborative projects.
Finally, this generalist training is backed up by more technical assignments, such as the analysis of local
viti/viniculture systems.

Admission

Target audience

Recruitment for the L3 prépa DNO is deliberately multipartite: students from IUT chimie,
IUT Génie Biologique, various L2s, CPGE/BCPST or engineering schools
can apply for this course. The teaching team is also keen to
maintain access to this course for motivated students from the most technical streams (mainly BTS
viticulture œnologie).
The L3 Prépa DNO also successfully welcomes working people who, after an initial
career, wish to reorient themselves within the framework of continuing education.
The fact that this course is open to sandwich courses means that the target group can be further broadened to include candidates
who have acquired 120 ECTS in scientific and economic studies, or equivalent skills
obtained through professional experience recognized by VAE.
Applications are selected in two stages: pre-selection on the basis of applications (via
electronically on the Faculty of Science website from the beginning of May), followed if necessary
by a motivational interview covering, among other things, prerequisites in chemistry.
