I have a theory about why Cabernet Franc wines tend to be more successful than other, kick-you-in-the-face varietals in Washington and elsewhere in the States. It's not because the grapes are better; it's because the winemakers who are thinking about Cab Franc are less interested in maximum extraction, maximum alcohol, maximum oak, maximum everything. Most winemakers in WA are following California's lead, which is "how can we make this a MONSTER?" Cab Franc in contrast is interesting to people who are more interested in subtlety (a rare thing in America).

It's very popular in parts of the Loire Valley, like Chinon and Saumur-Champigny, though most Americans first encounter it as a blending grape with Cabernet Sauvignon in Bordeaux blends, or Californian attempts to recreate those blends. These attempts usually succumb, in my opinion, to the blowout capabilities of Cabernet Sauvignon, which is perfect for Robert Parker-style 16.5% megaton bombs. You can't really do that with Cab Franc, thank God, so you have to fall back on subtlety and elegance.

Note that the Cab Franc territory in the Loire abuts and shades into the Pinot Noir regions as you get closer to Burgundy -- Sancerre reds are Pinot Noir, for instance.

I know you asked about Washington wines, but I don't know much about them, so I'm rambling about what I do know. I'm looking forward to hearing the answers myself!

I really like the Grenache, Cabernet Franc, and Mourvedre from Almquist Family Vinters, the folks who own The Book Bindery and the adjoining winery. Based on the history of those three varietals in this state as mainly smaller-role blending grapes (based on their relatively lower boldness as compared to Merlot, Cabernet Sauvignon, Syrah, or Sangiovese). The Grenache and Cabernet Franc varietals are generally softer on the palate. You can order them at The Book Bindery, or hit the wine tasting room next door first to make sure whatever you choose is up your alley.

Another one I really enjoyed that you might like, is the 2007 Gilbert Cellars Cabernet Franc.

I also really like Kevin Cedergreen's Thuja. It's an inexplicable name (well, I'm sure there's a name, but whatever) for a Merlot-Cab blend. The 2005 and 2006 are the years I've had that have not been overwhelming.

This wine celler

http://www.citycellar.com/index.htm

Has a section of 100 bottles that are all priced $10.00 or less. They try to make this selection well rounded as far as origins and types of wine are concerned. There are some locals in there. If you don't want to break the bank while trying some stuff on a whim maybe swing by this place.

I've only been there once but the staff was super helpful and very nice. I think they really like what they do.
