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.

2023 WAVE Research Seminar

This year’s WAVE will feature the results of recently completed research that studied the effects of harvest and alcohol concentrations on the sensory attributes of red and white wines. Seminar attendees will also participate in sensory evaluation of research wines made as part of the projects.

August 10 – Walter Clore Wine and Culinary Center, Prosser

1:30 p.m. – 4:00 p.m., Wine Social to follow

2023 WAVEx Events

February 16 – 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 23 – 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.

April 20 – 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.
