Ravenholt Lecture Series

The Ravenholt Lecture Series brings grape and wine industry professionals to WSU to share their research and professional perspective. The series is made possible through an endowment from the Albert R. Ravenholt Foundation. Ravenholt, an early pioneer in Washington’s wine industry, was founder of Sagemoor Vineyards. 2-3 Ravenholt lectures are held annually on topics relevant to growers and winemakers in the Pacific Northwest. Check out a list of upcoming V&E events here.

Winemaking Seminars

We strive to bring the latest research and technology to winemakers and industry professionals. These seminars are held throughout the year and led by WSU faculty, industry experts, and invited speakers from various research and education centers.

WAVE Seminars

WAVE (Washington Advancements in Viticulture and Enology) is an annual seminar highlighting research outcomes supported by Washington’s wine industry. Sponsored by the Washington State Wine Commission and Washington State University, this educational seminar is designed to put viticulture and enology research into the hands of those who need it and to raise awareness of the value of research amongst grape growers and winemakers.

WAVEx Seminars

In response to feedback from past attendees, a more condensed version called WAVEx is held in other wine-producing regions across Washington state. WAVEx is tailored for vintners and includes both research and extension outreach, such as practical winemaking tips.
