A sign of the times
You know you're in wine country when the appellation is hanging on the signpost out in front.
Think that affects the price of the property? You betcha!
Now that sign's there partly because there are 26 acres on the property, with some of that acreage useable for vineyard, should the proper permits be granted. But it also speaks to the desire by many moving into the area for some instant status with friends & relatives who don't live around these parts.
It also should be a reminder that you're on a river (or near one) and that flooding isn't unknown...
If you look at the picture you'll notice the high water marks on the building. That's a pretty good indicator that there's a potential for future flooding events.
(The above barn pic is about 10 miles upriver from the property for sale, and is located on the Russian River in the Alexander Valley. The Russian River floods more frequently than the Napa River, happening about twice each decade to some degree or another. Not all declared floods produce damage to structures, but there have been some whoppers.)
