Grape quality can be quantified using a number of metrics, the same can be said of wine quality. Since wine quality is directly impacted by grape quality, viticultural management practices play an important role in elevating wine quality. Dean Volenberg’s applied research viticulture program examines the impact of canopy management, vine balance, and integrated pest management practices on grape quality. Although his research is often directed at specific industry concerns having long term implications, his Extension program is dynamic and responsive to seasonal industry needs.

Dean has an Extension and research appointment in viticulture and winery operations. His appointment is collaborative effort of the Grape and Wine Institute (GWI) and Plant Sciences Extension. Dean provides viticulture and winery Extension outreach throughout the state that includes grape production and processing. In his position Dean works closely with other members of the viticulture and enology program to transfer knowledge gained through GWI research to grape producers and winery operators.
