The effect of a spring frost that occurred in 2021 in northern Italy was studied in a cv. Barbera vineyard and data were compared to those derived from the previous season (2020), when no frost damage occurred. Due to rising temperatures, the advancement of budburst widens the period that exposes developing shoots to spring frost injuries. In vineyards, damage can vary considerably according to frost severity and duration, as well as the stage of shoot development. Thus, a careful assessment of the frost consequences should be carried out in order to make the best decisions either to manage the eventual residual crop or to ensure next season’s full cropping

Abstract
The effect of a spring frost that occurred in 2021 in northern Italy was studied in a cv. Barbera vineyard and data were compared to those derived from the previous season (2020), when no frost damage occurred. Due to rising temperatures, the advancement of budburst widens the period that exposes developing shoots to spring frost injuries. In vineyards, damage can vary considerably according to frost severity and duration, as well as the stage of shoot development. Thus, a careful assessment of the frost consequences should be carried out in order to make the best decisions either to manage the eventual residual crop or to ensure next season’s full cropping
