Ripening grapes in Eastern Canada: How climate affects grape potential for winemaking


Part of the ‘From Grapes to Wines: Cool Climate’ webinar series, join Perennia’s Viticulture Specialist Francisco Diez and Dr. Karine Pedneault from Université Sainte-Anne for the upcoming session ‘Ripening grapes in Eastern Canada: How climate affects grape potential for winemaking.’

SESSION DESCRIPTION:

The berry ripening process begins as soon as the flowers are fertilized and the tiny berries form. In the grapevine, ripening is generally considered directly related to an overall accumulation of heat during the season (growing degree days). The development of the berries, initially green and hard (pre-veraison) and further coloured and translucid (post-veraison), follows a precise set of metabolic processes, where certain compounds of importance for wine quality accumulate before veraison and others later in the season. The pattern in which heat accumulates can impact these metabolic processes and, therefore, berry quality at harvest.

In this webinar, Prof. Pedneault will talk about their study on the impact of growing degree-days accumulation under different conditions on the chemical composition of L’Acadie blanc grape berries in Nova Scotia, using an experimental approach. They also studied the impact of harvest date on the content of compounds of oenological importance in berries in different grape varieties and conditions. This webinar will present the results of these studies carried out on this topic in Eastern Canada.


SPEAKER DETAILS:

Prof. Pedneault has a Bachelor’s degree in Biochemistry and a Master’s and a Ph.D. in plant biology from Université Laval, with a specialization in plant secondary metabolites. She started her career in wine science at E & J Gallo
Winery (Modesto, California) and, after coming back to Canada, she developed an expertise on the maturity of hybrid grape varieties in Quebec (2011-present) at the Centre de développement bioalimentaire du Québec (CDBQ, La Pocatière, QC, 2012-2016) and at Institut de recherche en biologie végétale (associate, IRBV, Montreal Botanical Garden; Montreal, QC, 2016-present), and as a professor at the Department of Science of Université Sainte-Anne (2016-present).

Her research focuses on the biochemistry of cold and disease-resistant grape varieties, their cultivation in challenging environments, and the relationships between grape composition, wine quality and terroir. Since 2012, she has contributed to the training of more than 30 graduate students and interns. She is the author of more than 100 publications, including more than 25 publications in peer-reviewed journals and book chapters. She currently leads a berry ripening project in Eastern Canada within the Canadian Agricultural and Agri-Food Canada Cluster on viticulture and enology (2018-2023). Her work is also supported by NSERC and Research Nova Scotia. In 2019-2020, she led the construction of the first research winery at Université Sainte-Anne.
