NAPA, CA (March 24, 2016) - On Wednesday April 13, the Napa Valley Grapegrowers will have the honor of introducing one of the most recognized experts on grapevine physiology, Dr. Markus Keller, Professor of Viticulture at Washington State University, at the Sustainable Vineyard Practices Series ("SVP").

This is a rare and special opportunity that anyone in quality winegrowing should not miss. Dr. Keller is one of the leading researchers on both fundamental and advanced grapevine physiology and provides valuable knowledge and explanations that will enable growers to make more informed decisions in the vineyard for the future. As we face the present changing and ever challenging weather and climate conditions, his research is critical. While he is renowned for his essential text, The Science of Grapevines: Anatomy and Physiology, hearing him speak in person and answer questions is a must for any grapegrower seeking to achieve optimal grapevine performance.

Dr. Keller will focus on vine and berry physiology and discuss how vines acquire mineral nutrients from the soil and use them for growth, fruit production, and ripening. The influence of water deficit on these processes will also be covered, as will the emphasis on key nutrients and how these affect fruit composition.

SVP proudly features two other highly respected industry professionals to elaborate on grapevine nutrition. Stan Grant, Owner of Progressive Viticulture, will review how to develop a grapevine mineral nutrient management plan and Patrick Riggs, Viticulturist with Domaine Chandon, will highlight the importance of understanding fruit nutrient content at harvest and how nutrient data compares across various Napa Valley ranches.

For 6 years, the Sustainable Vineyard Practices Series has consistently sold out and been praised by the industry as one of the most informative events of the year, keeping the Napa Valley at the global forefront of sustainability and progressive viticultural practices.
