Emerson, near Monmouth, Oregon, not far from Salem in the Wilmette Valley. They are on the Harvest Home program, and we were offered a parking place with spectacular views of their 25 acres of grapes and beautiful mature oak forest. We were also treated to a tasting like I remember from so many years ago, attentive and informative with no pressure to buy.
The Longsword Winery in the Applegate Valley of Southern Oregon, was the first winery that hosted us for a night under the Harvest Hosts program. For a $20 membership you receive access to a growing number of wineries and farms who will allow you to park your RV overnight without a fee.
