My research primarily aims to explore wine grape aroma physiology, and the ranges of influence that environmental conditions (such as rainfall, temperature, and solar radiation) may have on the biosynthesis and accumulation of aroma compounds within grapevine berries. Of particular interest is the aroma compound responsible for the aroma of black pepper, a sesquiterpenoid named rotundone that is present in myriad plants in addition to wine grapes of both red and white cultivars. Being a potentially important contributor to wine aroma and quality, understanding the relationships between environmental factors and rotundone--in addition to other similar aroma compounds--could assist growers with tailoring production methods to facilitate enhanced aroma development and quality grape production.
