Josh Ward, left, and Bob Miller join other workers in harvesting Merlot grapes in November 2016 at Lake Roosevelt vineyard near Creston, Washington. The south-facing vineyard sits atop a cliff with basalt walls behind it. High above the cliff on the plateau stretch miles of wheat fields. Below it lies Lake Roosevelt, a Columbia River reservoir built behind Grand Coulee Dam. Inset at left: Merlot grapes await crushing. &lt;b&gt;(Shannon Dininny/Good Fruit Grower)&lt;/b&gt;
