Sour rot is a recurring problem in early season thin-skinned, tight-clustered grape varieties, such as Pinot noir, Pinot gris, Riesling, Gewurztraminer, Gamay and Baco noir, and has been responsible for more than $1.5 million in crop loss in a given season in the Ontario region, when weather conditions promote infection.
CCOVI has assembled an Outreach Brief: Tips For Managing Sour Rot in the Winery, to help the industry addresses the challenges associated with sour rot, such as helping winemakers minimize the negative impacts of sour rot on wine quality and decrease a loss of income from reduced yield.
This brief was created with support from Ontario Grape and Wine Research Inc. and the Canadian Grapevine Certification Network(CGCN-RCCV), as part of the Grape and Wine Science research cluster.
