This is one of the closest wineries to Portland, but once you're on the property, you're a world away, with views of the surrounding Chehalem mountain ridge. Tastings offer a selection of Oak Knoll wines, some of which are only available here. Oak Knoll is lauded for its Pinot Noir, Chardonnay, Riesling, and Pinot Gris. It also produces an unoaked Chardonnay, a slightly sweet, spätlese-styled Riesling, and a Native American varietal, Niagara. The vineyard's large manicured lawn is ideal for picnics.
