Water availability is arguably one of the major factors limiting canopy growth and grape production in vineyards. Climate change is forecasted to make precipitation more erratic and increase temperatures in many wine regions, making drought events more frequent in vineyards. In dry wine regions, growers often apply sub-optimal irrigation levels, known as deficit irrigation strategies to limit the canopy growth and improve grape and wine quality. In red grape varieties, deficit irrigation improves the accumulation of phenolics in the grapes and the quality of wines. Recent studies have indicated that deficit irrigation strategies could also affect the quality of white grapes and wines. Indeed, water deficit induces the accumulation of grape terpenes that characterize the aroma of white wines such as Viognier, Riesling, Gewürztraminer, and Muscats. Our study in the Okanagan Valley has shown that deficit irrigation strategies can be used as a strategy to save irrigation water and improve wine aroma in white grape varieties.
