Researchers want to predict the productive potential of grapevines

A study led by researchers from the University of Porto and INESC has validated a method to predict grapevine productivity months before harvest. The method involves forcing dormant buds under controlled environmental conditions to stimulate development and assess potential flower clusters. Testing was conducted between 2023 and 2025 on around 200 vines of Jaen and Alfrocheiro varieties in the Dão region, showing a 90% accuracy in predictions. The results, which also led to the development of a non-destructive optical sensor called BudScan, were published in OENO One. This research aims to assist producers in adapting to climate variability.
