The Department of Viticulture and Enology offers a comprehensive education and research program designed to prepare students for successful careers in the wine and grape industry in Washington and beyond. Enhanced by renowned faculty and state-of-the-art facilities, the Department takes a hands-on, multidisciplinary approach in offering students technical, scientific, and practical experiences. The undergraduate degree path will lead to a Bachelor of Science in Viticulture and Enology. This degree pathway is offered exclusively at the Tri-Cities campus. The department also offers a minor in Viticulture and Enology for any student desiring to learn more about the juice and wine industry from the growing of grapes to harvest, processing and product evaluation.
Student Learning Outcomes
- Apply critical thinking and problem solving to address issues facing the global viticulture and enology industry.
- Demonstrate technical competence in viticulture and enology, especially as it relates to viticulture, winemaking practices and the chemical, microbiological and sensory analysis of wines.
- Evaluate and adapt foundational viticultural and enological practices as appropriate to be environmentally and socially equitable.
- Promote and value life-long learning through engagement with government agencies, university research and extension, and industry in a professional manner.
Undergraduate Transfer Students
Students planning to transfer to Washington State University into Viticulture and Enology should take courses that meet the University Common Requirements (UCORE), and core requirements for Viticulture and Enology. Students are strongly encouraged to consult with and advisor and the Department Chair of Viticulture and Enology for further guidance.
Graduate Study
The Viticulture and Enology Department is active in research and hosts a diverse graduate student community. Depending on the area of interest, graduate degree paths lead to degrees of Master of Science in Crop Science, Master of Science in Food Science, Doctor of Philosophy in Crop Science and Doctor of Philosophy in Food Science.
Schedules of Studies
Honors students complete the Honors College requirements which replace the UCORE requirements.
Viticulture and Enology (Tri-Cities Only) (122 Credits)
A WSU Tri Cities student may be admitted to the Viticulture and Enology degree program upon making their intention known to the department. Students from other campuses may work with a V&E advisor, and begin taking courses but acceptance to WSU Tri-Cities is required before admission to the major is granted.
