If you are looking for an alternative to the wines in your grocery aisle, consider going online and exploring the flavors of Washington wines that didn't make it to the store.
One of the options is organic wines.
China Bend Vineyard is a winery in the Yakima Valley that uses organically-grown grapes and doesn't contain sulphites. The bottles themselves are beautifully designed, and moderately priced starting at about $20 a bottle. You can order from them online.
Another option to consider is joining a wine club, where periodically you receive a different wine from a particular winery. One of my favorites is Stemilt Creek Wines, from Wenatchee. They offer a variety of award-winning wines.
If you are going to go this route, remember that you or an adult over the age of 21 must be present at the time of the delivery. So, enjoy exploring the local wine options this state has to offer from the convenience of your home.
