Evaluation of vineyards, fruit and wine affected by wild fire smoke
Wineries may randomly reject fruit from vineyards near wild fires exposed to smoke. It is difficult to determine if fruit has been compromised in quality when exposed to smoke
Climate change
The temperature‐based grapevine sugar ripeness (GSR) model for adapting a wide range of Vitis vinifera L. cultivars in a changing climate
Temperatures are increasing due to climate change leading to advances in grapevine phenology and sugar accumulation in grape berries.
Changes in flavonol profile are a reliable indicator to assess the exposure of red grape berries to solar radiation and canopy architecture
Exposure to solar radiation affects berry composition through photomorphogenesis or changes in temperature. Flavonol synthesis is upregulated by UV‐B radiation
Heat waves and drought stress impact grapevine growth and physiology
Recurring heat and drought episodes during the growing season can produce adverse impacts on grape production in many wine regions around the world.
