Importance of Clean Plants and Quarantines
Regardless of whether you are a commercial grape producer or a backyard enthusiast, Washington State has strict quarantines regarding where your grapes come from. DO NOT bring back grape plants from your trips abroad (whether domestic or international). Doing so may result in very strict fines, but more importantly, may bring in diseases and pests that could severely hurt the commercial grape industry. ONLY buy stock from reputable nurseries. If you purchase from sources outside of WA, you must notify the Washington State Department of Agriculture of their arrival, and schedule an inspection. More information on “planting clean” and WA quarantines are found here:

Variety and Rootstock Selection
Variety selection is dependent on what is best suited for your site and what you can market/sell. Consult potential fruit customers and winemakers before heavily investing in large plantings.
- Clean Plant Center Northwest Grapes – Check out the current availability of different varieties in the Washington State Grape Foundation Block.
- National Grape Registry – A great database out of California of different grape varieties and clones available in the USA.
- Grape Genetic Testing and Identification – A service provided by the Foundation Plant Service out of UC-Davis that can determine the variety/cultivar of an unknown grapevine. Clonal identification is currently not available.
- Vitis International Variety Catalog – A searchable database of different varieties, and their various synonyms.

- Northern Grapes Project – A joint venture designed to aid in viticulture production of cold-hardy (winter low temperatures) varieties.
- Rootstock Selection (PDF) – OSU #EM8882 – Rootstocks are recommended for western Washington, due to general lower soil pH and cooler, shorter seasons. Conditions in western Oregon are similar to Western Washington.
