Canada’s wine industry contributes over $11 billion towards the national economy, of which $5.5 billion is generated solely by Ontario wineries. The cultivation of high-quality grapes to produce economically valuable wines does not come without challenges to growers and winemakers alike. Spatial variability in micro-climate and soil conditions have been a long-standing challenge to growers since the start of grapevine cultivation. With the added pressures of adapting to climate change, vineyards will require special management adaptations to achieve high quality berry yields and wines. The role of spatial variability on grape quality is especially important in Ontario, Canada. Here, climate is shifting towards longer and warmer growing seasons, with variable precipitation patterns, presents threats to growers in addition to those that already exist due to vineyard spatial variability. Additionally, water deficits are integral to achieving optimal quality through the development of desirable flavour and aroma compounds, which may be at risk under climatic uncertainty. This research includes a combination of methods aimed at assessing hydrometeorological components site-wide, as well as between different blocks, rows and among individual grapevines, to best understand spatial differences across two vineyards in the Niagara growing region. Evapotranspiration findings will be compared to water potential (grapevine stress), brix and grape chemistry values for the 2022 vintage. This research, presents an opportunity for growers to understand the current state of their vineyards and the spatial variability across their crop, allowing them to make specific, non-uniform, management decisions to enhance grape yield and quality each growing season.
