From vines to trees: Dayton, Oregon is home to Vista Hills Winery, which overlooks the scenic Willamette Valley. The unique Tree House Tasting Room is the centerpiece of this 6,000-square-foot facility, which features a barrel storage on the lower level. Several trees had to be removed from the property for the construction of the winery; O’Brien repurposed those trees to become part of the stately and unique main winery building.
