Wineries Oregon or Washington??
 

I'm planning a 4-5 day September trip for some wine tasting and would like to know which area would be better. I've done the Napa/Sonoma trip several times and expect it to be much smaller.
I'm interested in the smaller more scenic wineries, not the larger industrial types. Are there enough wineries in Washington to occupy a few days? Where would the better wines be?
Any info would be appreciated. Thanks!

There's a real difference (for the most part) in the geography of the two wine-producing areas. (And here I refer to the grape-growing areas, not the location of wineries that are at a great distance from the vinyards, like some in the Seattle area.)

In Oregon many of the wineries near the vinyards - Yamhill County for example - and are located in the western part of the state, where in September it will be warm but not hot. In Washington many of the vinyards/wineries are located east of the Cascade mountains, where in September it's likely to be quite warm, even hot depending on when in September. The Yakima and Walla Walla areas are much more continental (verging on desert) than their western Oregon counterparts.

In terms of scenery, boy, hard to pick 'em. Red rocks, canyons, "old west" scenery vs. green hills, trees, covered bridges...

With the WA wineries you can add in a day in the Columbia Gorge/basin, with the OR wineries you could spend a day out on the coast... sheesh. Can't you find more time and do both?

Vineyard. Ugh.

You might decide based on what kinds of wines you prefer. Yakima and Walla Walla areas are best known for varietals that do well in long, warm, growing seasons: cabs, chardonnay, zins.... Oregon's Willamette Valley has a milder climate more suitable to producing pinot noir, pinot gris, and riesling. I live near the heart of Oregon's wine country; rolling green hills dotted with wineries and other agriculture. None of the wineries around here compare to the "larger industrial types" of Napa or Sonoma, and some are in spectacularly scenic settings.
