Perennia led the ‘Terroir Study of the wine growing region of Nova Scotia: A complete study based on the interaction of soil, climate and plant growth. This study’s main goal was to evaluate the key wine growing parameters in Nova Scotia and provide the best management techniques and tools to the grape and wine growers of the Province for our local conditions, based on scientific results and technical information.
In the Terroir Study, Perennia collaborated with established grape growers to evaluate vineyard performance and improve their management practices for considering the final wine. It took place during three consecutive seasons (2017-2019). Fourteen different vineyards were selected based on the interaction of soil characteristics, climatic conditions and agricultural practices.
The most planted grape varieties of Nova Scotia were selected, four interspecific hybrids and four Vitis vinifera varieties. Perennia’s team evaluated plant physiological characteristics such as percentage of budburst, determination of main phenological stages, plant growth, uptake of nutrients through soil, petiole and blade analyses, water stress measurements and fruit ripeness. Agronomic characteristics were also measured. These included plant spacing, plant density, trellis system, vineyard management (weeds, pest and disease and canopy) and yield per vine. To complement these evaluations, winemaking was performed, which made it possible to understand the process and evaluate the improvements in the vineyard.
All this information was analyzed, reported and presented to the grape growers to demonstrate which practices can help vineyard management in the specific conditions of Nova Scotia. These results are used in publications and presentations to provide accurate support to the local wine industry.
