Honorary Research Lecturer to Discuss Chemical Bases of Wine Aroma Perception

Analytical chemistry professor and Head of the Laboratory of Aroma Analysis and Enology (LAAE) in Spain, Dr. Vicente Ferreira from Universidad de Zaragoza, Spain, will present this year’s Honorary Research Lecture, “What We Know About the Chemical Bases of Wine Aroma Perception,” on June 28 at the 74th ASEV National Conference in Napa, California.

Dr. Ferreira specializes in chemical analysis of the molecules responsible for the different perceptions related to odor, flavor and taste, and in the integration of the chemical information used to interpret sensory perception. This knowledge has been primarily applied to wine flavor, a field in which LAAE leads globally.

Register now for the 74th ASEV National Conference to learn more about wine perceptions from an international expert in the field.

Michael Silacci of Opus One to Keynote on Future of Napa

Climate change has become another opportunity for Napa Valley viticulturists and winemakers to lead the way in wine industry competition, similar to the Judgement of Paris in 1976 when two Napa Valley wineries shocked the world by taking the top spots. Michael Silacci, winemaker at Opus One, has spent most of his career walking the vineyards in the Napa Valley. He will reflect on his journey and how he and his team of 40-plus are preparing for the future.

Listen to his keynote address, “Judgement of Napa,” on June 28, 2023, at the 74th ASEV National Conference at the Napa Valley Marriott in Napa, California. Register today!

Takeaways from the April Webinar: Soft, Sweet and Colorful

In April, speakers Esther Hernández Montes of Polytechnic University of Madrid, Spain; Ben-Min Chang of Agriculture and Agri-Food in Canada; Markus Keller of Washington State University, Prosser; Nataliya Shcherbatyuk of Washington State University, Prosser; and Yun Zhang of Ste. Michelle Wine Estates in Washington presented their paper on “Soft, Sweet and Colorful: Stratified Sampling Reveals Sequence of Events at the Onset of Grape Ripening.” Key findings include:

  1. Individual berries within a cluster ripen at different times and have different chemical and physical properties at each stage of ripening.
  2. The current approach of lumping all berries of the same cluster together during analysis overlooks important details of the ripening process.
  3. The term “veraison” may not be suitable for describing individual berries, as multiple changes are occurring at different times. It is more appropriate to use the term for the overall population of berries in a vineyard.
  4. The research was conducted by a diverse team from different countries, reflecting the global nature of viticulture and the collaboration happening in the wine industry.

Dr. Markus Keller noted during the Q&A session, “One thing that I find exciting about this paper, is there are five authors and each one of us has a different accent. We are from five different countries and did the actual study in America, even though none of us were born in the U.S., which reflects the diversity we now have at ASEV and also in the world of viticulture.”
