Conference presentation

Every 4 years, the Oeno congress brings together the scientific community of oenology researchers to share knowledge and develop new perspectives.

Every 4 years, the Oeno congress brings together the scientific community of oenology researchers to share knowledge and develop new perspectives.

From July 10 to 13, 2023, the Oenology Research Unit of the Institute of Vine and Wine Sciences from Bordeaux university is pleased to welcome you to the 12th International Symposium of Oenology of Bordeaux which will be held in conjunction with the 9th International Macrowine Conference on Macromolecules and Secondary Metabolites of Vine and Wine.

This conference will be organized around plenary lectures with invited speakers as well as with oral, flash or poster communications selected by an international scientific committee.

During ŒnoMacrowine 2023 congress, a particular emphasis will be given to communications regarding Macromolecules and secondary metabolites of grapes and wines.

The wine industry sector has to face many challenges in the context of agroecological transition and taking into account consumer expectations and societal demands. Important changes in connection with the evolution of ripening characteristics due to climate change, new viticultural and enological practices will potentially strongly impact the grape berry composition, the wine quality and the microbiological processes. In this context, ŒnoMacrowine 2023 aims to explore all aspects related to these transitions. We are particularly requesting, through the various traditional themes of Œno congress, communications that address these issues and provide elements of knowledge, allowing the formulation of new research questions, adaptation perspectives, innovative processes.

Œno conference : International Symposium of Enology of Bordeaux

In 1963, to celebrate the 100th anniversary of Louis Pasteur work on wine, the 1st International Symposium of Enology of Bordeaux was created by Pr Jean Ribéreau-Gayon and Dr Emile Peynaud. After the first edition, the symposium continued in 1967, 1977, 1989 and then in 1995, 1999, 2003, 2007, 2011, 2015 and 2019.  Œno symposia are consistent with the principle of general-interest symposia covering the fields of enological science allowing exchanges within a multidisciplinary scientific community dedicated to wine sciences. Thus, 4 traditional themes - Plant environment and grape quality, Grape and wine microorganisms, Wine chemistry, Sensory analysis - are the foundation of the Œno symposia. The research questions have evolved : oenological research initially focused on wine clarity and instability problems, then on fermentation control, evaluation of grape qualitative potential and its evolution during vinification and aging as well as the parameters of sensory perception. In June 2019, Œno2019 edition, took the opportunity of an joined organization with In Vino Analytica Scientia Symposium under the denomination ŒnoIVAS 2019, to organize a congress with a specific focus on grape, wine, wine-spirit analysis. 

Œno2023 symposium 12th edition shall be coupled with Macrowine2023 congress including in the traditional themes of Œno congress a specific focus on grape and wines Macromolecules and Secondary metabolites. In addition, as previously mentioned, the wine industry being affected by important changes, communications addressing these specific issues will be particularly considered during this congress.

Macrowine  conference

The Macrowine congress, International Conference of macromolecules and metabolites, was initiated in 2006 at the University of Reims-Champagne-Ardenne by Pr. Philippe Jeandet, Pr. Christophe Clément and Pr. Alexandra Conreux.

Macrowine is a prestigious international conference initially focused on the wine macromolecules. 

The core topic has also been the understanding of the structure, evolution, role and physico-chemical interactions of grape, vine and wine macromolecules, then expanded to grape vine and wine secondary metabolites. The general purpose of the conference is to bring closer scientists and build international networks in order to help wine industry to become more sustainable and more competitive, able to produce better, richer, more appealing, safer, healthier and more stable and diverse products in a context strongly restricted by climate change, and the conference stimulates the presentation of results from international collaborations and networks. The congress which has been held every 2 years, constitutes a platform for exchange and presentation of the latest advances concerning macromolecules and compounds of secondary metabolism. “

Macrowine congress, as itinerant congress, was first held in Reims (France) in 2006, then in Montpellier (France) in 2008, in Turin (Italy) in 2010, in Bordeaux (France) in 2012, in Stellenbosch (South Africa) in 2014, in Changins (Switzerland) in 2016, in Zaragoza (Spain) in 2018 and in Verona (Italy) in 2021 before the Bordeaux research unit in enology obtained the approval to organize the 9th edition in 2023.
