The Washington Advancements in Viticulture and Enology (WAVE) seminars, which are co-sponsored with Washington State University, follow a half- to all-day format to highlight viticulture and enology research. WAVEx is the condensed version, often in a webinar format, with targeted topics and practical application. WAVEx allows Washington Wine and WSU to tailor research programming for specific wine regions. WAVEx has visited the following regions: Prosser, Richland, Walla Walla, Lake Chelan, Columbia Gorge and Woodinville.

2024 WAVE Connect Research Seminar

This year’s WAVE highlights the industry connection to WSU’s Viticulture and Enology faculty and students. Research topics discussed include optimizing vineyard nutrition, grape maturity and alcohol and long-term maceration on Cabernet Sauvignon, integrating nematode IPM, development of vineyard and winery tools to manage smoke impacts, and sustainable grape mealybug mating disruption. A panel discussion on student internships will be held and focus on graduate student research.

April 11 -WSU Wine Science Center, Richland

1:00 p.m. – 5:00 p.m., Wine Social to follow

Past Webinar Recordings

March 21, 2024 – Putting Beneficials to Work – Dr. David James, Washington State University  entomologist, will summarize his findings on how to bolster the effectiveness of biological control with predators and other beneficial bugs. Watch the webinar recording here.

December 6, 2023 – Spotted Lanternfly: What have we learned? – Dr. Michela Centinari, associate professor of viticulture at Pennsylvania State University, has been in the trenches dealing with this relatively new invasive pest in Eastern U.S. grape regions. She will share the successes and failures of management strategies of wine grape growers and why it is critical to keep the pest out of Washington vineyards. Watch the webinar recording here.

April 20, 2023 – Soil Fumigation for Nematodes? – Dr. Michelle Moyer, WSU viticulture extension specialist, shared results from her nematode research that studied the effectiveness of fumigation for nematode control, spanning multiple years. Watch the webinar recording here.

March 23, 2023 – Deep Root Zone Irrigation – Dr. Pete Jacoby, WSU plant ecologist, summarized his work on developing an alternative irrigation delivery system, and what he’s learned from soil moisture irrigation sensors during this one-hour webinar. Watch the webinar recording here.

February 16, 2023 – Stuck Fermentations –  Dr. Thomas Henick-Kling, WSU enologist, shared his decades of knowledge about stuck fermentations and what can be expected in making wines from Washington grapes. While there are several known causes of stuck fermentations, he recently found stuck fermentations in Washington wines that are caused by an imbalance of glucose and fructose. During the webinar, Henick-Kling discussed causes of sluggish and stuck fermentations, how to diagnose and correct them. Watch the webinar recording here.

March 24, 2022 – Soil Inoculants – Dr. Tanya Cheeke, assistant professor of microbial ecology at WSU, led a two-year study to better understand the impact of mycorrhizal inoculations on wine grape production in Washington State.  Dr. Cheeke will share her research findings and discuss the role that soil fungi can play in Washington vineyards and their potential contribution to sustainable wine grape programs. Watch the webinar recording.

May 20, 2022 – Phylloxera – Washington State University’s Dr. Michelle Moyer will discuss how to use the Phylloxera Risk Assessment Map to determine risk of phylloxera in Washington vineyards. Dr. Doug Walsh, WSU entomologist, will share results from pesticide efficacy trials. Watch the webinar recording here.

August 5, 2021 – What’s in Your Brett Toolbox? – Dr. Charles Edwards, WSU food scientist, summarizes his decades of work focused on developing management tools for wine spoilage. Watch the webinar recording here.

July 14, 2021 – Working with High pH Wines – Dr. Thomas Henick-Kling, WSU, shares insight from recent research to help winemaking work with high pH wines. Watch the webinar recording here. Watch the webinar recording here.

May 27, 2021 – Powdery Mildew: Innovative Strategies – Drs. Michelle Moyer, WSU, and David Gadoury, Cornell University, discuss promising new technology to sustainably control grape powdery mildew that utilizes UV-C light arrays. Watch the webinar recording here.

April 8, 2021  – Crop Estimation Smartphone App – Dr. Manoj Karkee, WSU, will share his progress in developing a smartphone app for growers to use to estimate crop. Watch the webinar recording here.

March 4, 2021 – Managing Grape Leaffolders in Washington, Dr. David James, WSU. Watch the webinar recording here.

January 20, 2021 – Does Mechanization Pencil out for You?, Dr. Clark Seavert, Oregon State University.   Watch the webinar recording here.
