Washington State wineries

Agree about Rulo -- wonderful viognier. Go to Buty, Tamarack and Colvin in Walla Walla -- all near the airport, and there are several other wineries in the immediate area, none of which will disappoint, IMO.

In Tri-Cities, Barnard-Griffin and Bookwalter are among my favorites.

This is on of the orgs that tracks WA wineries:

and here is another, if you are going through Seattle to get to Yakima: and the site of the Wine Commission: This is the site we use when we plan trips:

The food here is great:

Christophe Baron's wines at Cayuse, and all of the wineries that use Red Mountain grapes (Blackwood Canyon is trippy) are my current favorites. Sadly, one of the best was Seth Ryan, whose winemaker was young and died in a car accident recently. I have a friend who loves Wineglass Cellars, and Apex is nearly always mentioned as a top wine. The tricky part about WA wines is that many top winemakers simply transport the grapes from Eastern to Western Washington, so that makers like DeLille, Novelty Hill, JM Cellars, etc., make the best wines but aren't always sited in the growing region itself.

Have fun, and let us know what you find.

In addition to the excellent suggestion you've received -

Also, as you are coming into Walla Walla from the west, Woodward Canyon and L'Ecole 41 are right next to each other.

And Seven Hills in downtown Walla Walla.
