6.1.6 A final personal note
The journey of this research project has been interesting; exposing me to many aspects of viticulture, winemaking, research and sensory science. I’ve done this masters part‐time while employed full‐time as a winemaker at Fairview Winery. The study has broadened my outlook and knowledge and I would recommend others do the same. This research project has shown the benefits of collaboration between the
