The concept of one town with nearly a hundred wineries was truly unbelievable. When I think wineries I think Napa-Sonoma, Tuscany...a few buildings surrounded by acres of vineyards. But what they really mean are "wine tasting rooms." These are the tasting rooms (basically a tasting bar and boxes for purchasing) for many of the wineries out in the southern part of Washington: Tri-Cities Region, Yakima and Walla Walla Valleys.
I think the Mark Ryan tasting was my favorite Washington wine, it came highly recommended by locals and the New York Times. Everyone was extremely friendly, knowledgable & the wines were delicious. FYI, this was very difficult to find, because it's off in a niche plaza-type place.
We did the tour and tasting at Chateau Ste. Michelle Winery, which is probably the most famous; however, I wasn't too crazy for the wines. The historic home on the property is gorgeous so I would recommend stopping by, or checking out their summer concert schedule.
It was definitely worth our time to visit more Washington wineries and try some less mainstream type places. We only visited wineries, but the new trend popping up are whiskey distilleries. Woodinville is in the in the Sammamish River Valley and there is supposed to be a great bike path, which would have been a lot of fun to do.
Highly recommend visiting Woodinville if you are in Seattle for a few days, it's only 30 minutes northeast of Seattle. Only advise to drive when the traffic may not be at it's peak time.
